Nowadays, fashion is like the melting pot, and not restricted to rules or outdated concepts. "Almighty" is the core feeling brought by A/W 2020 shows. Designers smartly use innovative crafts to create leather and fur clothing. Here we conclude core trends on these international catwalks, such as the printed mink fur, leather, ruffle and splicing.

Based on sustainability, leather will be the main material in A/W 20/21. The leather which is designed and recycled sustainably is more advocated. The metal-free, chromium-free and vegetable dyeing are better for the environment. The superior quality sense is the key to leather and fur fabric. Berber fleece and fleece display comfort and quality sense. Optimism persists in turbulent times. The vintage era (including middle-class style) is a source of inspiration. The feminine silhouette reveals a retro feel, and the waist becomes the focus of design. The minimalism drives the rise of designs which is not restricted to seasons. Therefore, the all-over printed style declines. In this season, prints of leather and fur industry are dominated by natural landscapes and folk patterns.

Chanel A/W 2020 show is held in Grand Palais, Paris. The show is inspired by Ms. Chanel's racehorse "Romantica" and the photo of Karl Lagerfeld in knight boots, displaying the outline of equestrian clothing. Virginie Viard loves Les Biches by Claude Chabrol (French director), and presents the charming yet tough image of females in the movie in this season. Virginie Viard rejuvenates the signature silhouette coat with the unique tailoring. The wave-like neckline and plackets are soft and romantic.

LANVIN A/W 2020 womenswear show is held in Manufacture des Gobelins built in the 15th century in Paris. The show with a theme of Conversation Piece draws inspirations from the 1960s. The space age, elaborate makeup and supermodels from the 1990s work together to make the show a retro party. The creative director Bruno Sialelli connects the contemporary era and the history through a time-travel dialogue with the brand's founder Jeanne Lanvin. In this season, he reinterprets the creative ideas of Jeanne Lanvin and interprets Lanvin in different voices. The new collection takes example by Jeanne Lanvin's signature lines, formal dress style and modern graphic embroidery in the 1920s and 1930s. The graceful lines of the shoulder and structural simple cutting remind of the elegance of haute couture in the middle of the 20th century.

This report concludes the runway data of more than 220 brands in the four fashion weeks of A/W 20/21, and analyzes the catwalks with fabric as the main line. Different fabrics are applied to different styles, showing different wearing effects. Based on that, this report also combines with trendy fabrics in the new season to offer more design inspirations. Because of the retro trend, jacquard grows. Leather and pearlescent satin also change boldly. Novel deconstructed fabrics, futuristic parachute protective fabrics and traditional formal wear fabrics also get innovated in this season.

The A/W 2020 show of Louis Vuitton opens at the Louvre museum as scheduled. Nicolas Ghesquiere, the artistic director of womenswear, starts the show with a handwritten letter as the key. As the music plays, two hundred actors in costumes from different eras wait in the stands. Their looks span from the 15th century to the 20th century, and form a cross-time choir, so the dynamic classical beauty becomes the non-negligible background of the show, with soft singing and action to add a time filter to the show. The show is inspired by "Anachronism". People in the stands slowly salute to the models with eyes, as if people in the past were watching at the moment. Let's feel the collision of trends.

Silhouette and fabric are key elements to create the A/W 2020 series for Jonathan Anderson, the creative director of the Spanish brand Loewe. "I analyze Spanish culture and how the world looks at it", Jonathan Anderson explains backstage after the show, "I work on how to bring classic images of Spain into people's wardrobes and I really enjoy the process of building silhouettes of clothes. Last season I worked on silhouette and fabric very successfully, so this season I decide to continue this design idea." This collection is filled with a large number of simplified prints with traditional Spanish ceramic patterns as the main part. The partial silhouette of the design is based on the retro court looks. Loewe also works with ceramic artists to create lots of ceramic decorations for the ready-to-wear of this show. These are all in line with Jonathan Anderson's understanding of Spain.

In the whole A/W 2020 series of Sacai, the theme of "Universe" is not only the open-and-shut starry sky. They choose four from the thousands of images provided by NASA as the inspiration, so in this season we can see the brand turns space into beautiful fashion with the deconstruction design it has always followed. Inspired by the special issue of 2015 NASA, it works with fabric designer Alexander Girard to create a star map made up of mobile phones, letters and numbers. And the lower left corner which was to mark "Alien" presents "SACAI" now. Representative deconstruction and reorganization are used. The key design is combining light silk with high-tech fabric. Different items are combined to create a new silhouette which highlights the ethereal feel. But it doesn't blindly use lightweight fabrics. Instead, it makes use of the balance of fabric combination to design.

In this series, male and female models are in black, grey, classic Valentino red, low-key indigo and emerald. The clothing starts from basic silhouette to highlight the power of accurate cutting. Valentino, which still shows haute couture technique in the ready-to-wear series, is undoubtedly more low-key than previous seasons, but it is still meticulous about details. The series uses embroidery and print to sketch the realistic florals, adding a lively feel to the calm overcoat and the sleeveless dress.

From "leftover lady", "malechauvinist" to "sexual harassment" and "anti-domestic violence", more and more gender issues have emerged in public debate in recent years, accompanied by a feminist critique. Feminism is a series of knowledge methodology formed around the criticism of human patriarchy, and beyond the specific disciplines and research paradigms. It has become an important part of the social current of thoughts. Throughout the four fashion weeks for A/W 20/21, many brands have mentioned liberating females, female power and feminism, especially Paris Fashion Week. Christian Dior has a theme of "I SAY I" to express female power. Celine tells the story of womenswear during May 1968 events in France. Chanel puts forward the idea of liberation, and launches a series friendly to women. Valentino is the queen of the new minimalism. Miu Miu emphasizes the young lady's wear in the empire collection of the 1940s style. All of them are speaking out for women through fashionable way to show the gender mainstreaming from the perspective of gender equality under the turbulent times.

With the continuous expansion of the NCP, the four fashion weeks for A/W 20/21 are affected in varying degrees. Many brands cancel the show, while the brands joining the events advocate watching the shows live online. In view of the latest data, we extract five key color tones of blue-green, blue, yellow and orange and khaki. According to data of this season and previous three seasons, blue-green tones and orange tones grow, so we should pay attention to the color senses and clothing styles. For styles, commuting is the main style, which reflects persistence, patience and positive energy, and conveys the power of optimism.

The A/W 2020 collection of Celine still has the strong personal style of creative director Hedi Slimane. Male and female models are artistic and elegant, but with a deep rock sentiment. The whole show recreated the scene where the young bourgeois men and women strolled in the streets in the 1970s Paris. Gender ambiguity is still a hot topic in the fashion industry, and it gradually becomes a mainstream concept. Hedi said his show was unisex, where menswear can be worn by women and women's bags can be worn by men to be fit for consumers at different ages. This time he combines men's and women's fashion shows for the first time, deeply discussing the increasingly blurred gender in current fashion.

London Fashion Week is an international fashion week for fashion buyers, the news media, and the public. London fashion week ended in February this year. And it's clear that compared to previous LFW shows, this season is a little subdued. This season's London Fashion Week advocates environmentalism and no animal fur. Chinese media, fashion buyers and stars have been forced to change their work plans because of the outbreak. However, there are still many highlights.

This season Off-White teams up with Arc'teryx to put on a womenswear show with a theme of "Slighty Off", creating a collection that blends luxury and sports. The collaboration of Off-white with Arc'teryx breaks the stereotype that the outdoor clothing only focuses on functionality but has no distinctive appearance, and the impression that high fashion is dominated by suits, dresses and high heels.

Founded in 2010, the 10th anniversary of N°21 and Milan have been on a journey of change and adventure. The A/W 20/21 collection of N°21 uses irregular designs to point out a more novel and freer direction for females. The minimalist and fun style gets changed in this season. Young decorations like chains and clips are applied to clothing. Lots of neutral clothing with asymmetry, deconstruction and disproportionate cutting emerges in this season. The focus is the transformed collar structure and the retro disco style dominated by sequined fabrics.

In A/W 20/21 collection of Chloé, Natacha ramsa-levi, the creative director, explores the diverse female world. And she invites sculptor Marion Verboom to present sensual gold totem in the show, and musician Marianne Faithfull to read the classic literature. The iconic concrete lines from painter Rita Ackermann's works are also injected into the design of items and accessories. This season Chloe A/W 20/21 collection blends painting, sculpture and poetry into this show, adopts heather rose, dune, light brown, chestnut, dust blue and caramel, and applies paisley prints, the beaded collar and embroidery for a soft visual feel.

Milan is known as "the most artistic and modern" fashion city. This season A/W 2020 Milan Fashion Week revolves around "women", "strength" and "power" to redefine fashion and build a new world of independence, freedom and creativity. This season brands return back to the high quality and pursue design and quality sense rather than spread hot styles on social networks.

In A/W 20/21, women's knitwear pays more attention to design fun patterns. Designers use embroidery and napping to enrich details of animals and plants patterns. Folk patterns are notable. Traditional folk patterns are magnified, quite eye-catching. Individual illustrations are applied to knitwear, good-looking.

The A/W 2020 collection of Christian Dior keeps speaking out for women. The installation, created by "collective artist" Claire Fontaine, features a newspaper-covered floor and slogans from the late Italian art critic and feminist Carla Lonzi. A series of neon-decorated slogans in the show and the printed headbands display the independent character of modern women. The creative director, Maria Grazia Chiuri, draws inspirations from her girlhood diaries and integrates with Mr. Dior's beloved check elements. (Checks made up of pastel colors like milk cocoa, light green and warm grey are endowed with more creativity, elegant and nonchalant.) And tassels are prevailing in this season. Maria Grazia Chiuri continues the theme of "female power", speaks out for women, and expresses Dior's free soul of "I SAY I" with fashion.

The four fashion weeks for A/W 20/21 have been affected by the outbreak of NCP to varying degrees. Chinese buyers, stars and media workers have cancelled their schedules. Giorgio Armani's Milan show has changed to online launch. The theme of this Milan Fashion Week is also related to China: "CHINA, WE ARE WITH YOU". For Paris Fashion Week, despite the schedule change, brands such as MASHAMA, Shiatzy Chen and Uma Wang have also cancelled the event. However, there are still many highlights and vibrancy. This report will analyze from stitches, splicing and decoration to carefully select crafts in the four fashion weeks to help with the development of women's knitwear.

Simonetta Ravizza has been focusing on modern ready-to-wear designs that are relaxing, casual and simple, and using sophisticated designs that combine lightweight fabrics with different types of fur. Simonetta Ravizza has teamed up with Loro Piana to create a kind of material made from rare wool yarns. The yarn comes from ranches in a remote valley in central Italy, where animals are raised in an ancient breeding tradition and production is strictly limited, so the yarn has a rough surface. Simonetta Ravizza weaves it into natural-colored check and glen plaid which are made into lose jackets, overcoats and sportswear of the 1970s style. The brand is also committed to using of artificial fur, and to reducing the application of fur.
