Affected by this COVID-19 pandemic, fashion weeks are presented in a new way. With "less but better" consumption idea and higher demand for durable products, this season men's leather and fur clothing uses low-key and classic silhouettes to balance between the past and the present. Emotional designs create all-year items. Renewed designs, emphasized silhouettes, comfort and practicality offer consumers a relaxing and casual style.

Louis Vuitton 2021 Resort collection draws inspiration from Static Journey, takes "Game On" as the theme and explores inner emotions. Items of this collection are shot in the studio in Paris of Nicolas Ghesquiere, the womenswear art director. Nicolas Ghesquiere compares fashion creation to adventures in games. The collection consists of two parts, Quotidian and Playing Cards. Playing cards become main design elements of bags in the new season. Classic monogram mixes with four suits of playing cards, or bags are designed to be playing cards, hearts and dice. This collection takes us on a relaxing and unique resort journey.

MSGM S/S 2021 collection takes cues from Fluo: Storie di Giovani a Riccione by the Italian writer Isabella Santacroce, which tells a story of young people spending their summer days on sunny beaches and meeting again with their friends. Beside, designers also use paintings by Seth Armstrong and visual plants, reinforce the brand's aesthetics via bright color-blocking and express the new fashion attitude through layered match of varied items.

Jil Sander leads the minimalist fashion and influences the whole fashion industry. Its Resort 2021 collection balances between utility and minimalism and enhances utility without compromising minimalism. In this collection, we can see new elements mix with minimalist style to enrich the brand's culture.

With the change of lifestyle, sustainability and durability become the driving force of design. Transseasonal color proportion and natural tones are emphasized. Autumn tones, neutral camel tones and grey tones are increasingly important. Gem palette is enchanting and charming. Rocky Road and Chicory Coffee enhance the importance of deep brown colors. Preppy red is the key color of the right palette. A single color is used to create a simplified and individualized appearance.

Nowadays, fashion is like the melting pot, and not restricted to rules or outdated concepts.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.

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.

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.

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.

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.

The A/W 20/21 collection of Fendi kicks off with the psychedelic sound of Alessandro Cortini, Nine Inch Nails's keyboardist. This time Silvia Venturini, the creative director of Fendi, performs the theme of Gentle Power through the combination of structure and softness, and showcases the liberation of wearable female power. This season plus-size models join the catwalk lineup for the first time. The high-waist of the crisp overcoat and the well-fitting dress accentuates female form, which echoes the pink streamlined catwalk. Retro lantern sleeves run through the whole series. Color-blocking and contrasting of classic elements fully display the role switch between boudoir and meeting room. The strap boots with sheepskin cushion and satin high-heeled shoes highlight the vampire-like enchanting temperament, in line with the theme of boudoir. The waisted design, military outerwear with flare sleeves and the crisp fabric present the powerful temperament of females in the meeting room, quite emotional. Fendi's aesthetics balances between sexiness and calmness, toughness and softness, gentleness and power.

This season, the New York brand, Tommy Hilfiger, heads to London Fashion Week for its A/W 2020 collection. The brand keeps its vision of "vision to waste nothing and welcome all" and continues its exploration in sustainable fashion. In the A/W 2020 show, Tommy Hilfiger and Lewis Hamilton work together to create a new collection inspired by racers. More than 75% of styles are made in sustainable ways, including 100% organic cotton, recycled materials, down substitute and washed denim. The collection combines the traditional menswear of Tommy Hilfiger and the street style of Lewis Hamilton, and mixes burnt olive, neutral tones with highly saturated neon colors.

Gucci is always the most dramatic show of Milan Fashion Week. In A/W 2020, the creative director Alessandro Michele opens up the most confidential and private back stage to the public. The catwalk is like a doll house that combines carousel. The dreamlike presenting way and the gorgeous clothing collocation satisfy fans. The series uses a lot of kidswear details, seeming to satisfying kids' curiosity. Lace and velvet are used, which conforms with Belle Époque, one of S/S 2021 theme trends released by POP.

Since Riccardo Tisci took charge of Burberry's creative director in 2018, versatility and inclusiveness have made up Burberry's current form. After Kingdom, Tempest and Evolution, Riccardo Tisci takes Memories as the theme of A/W 20/21 Burberry. Images with mirroring and perceptive connotations are secretly displayed before the show. Skin, petal, dew... The shadow created by mirror symmetry sets the keynote of this season. The "Memories" world built by Burberry is like the alternations of virtual and real spaces with overlapping dimensions in the movie, Inception. On the catwalk, twin pianists Katia and Marielle Labeque cooperate with electronic producer Arcaper to put on a bizarre duet. For Riccardo Tisci, this series is a self-recall and reflection on memory, consciousness, perception, psychology and life.

Victoria Beckham is a high-end fashion brand founded by famous British singer and fashion designer Victoria Beckham in 2008. Victoria Beckham's own fame and her steady middle-class background make her designs unique. The 20/21 A//W series is inspired by that exhausted woman are seeking peace, and creates the style of confident wardrobe. The collection records the return of the black avant-garde silhouette and exposed neckline, negative space rhomboid knitting which is first raised by Stephan Cooke (a young London menswear designer), two pieces of Shetland knitwear (one in cornflower blue, the other in yolk yellow), flares sleeves, the dress with dense and regular smocking stitch, the finely cut check shirt, the skirt with a tough silhouette, and the layered color-blocked overcoat. These all bring a confident femininity of urban office ladies.

The A/W 20/21 collection of Coach 1941 is from the creative director, Stuart Vevers who joined Coach in 2013. In the new season, Coach still uses the modern technique to reshape a retro vibe and bring vitality of the 1980s New York. In the runway, gorgeous leather in original colors and the mid-length skirt with buckles keep the atmosphere. The brand also keeps the printed Japanese clothing and the old "Yeast Village" style. This season is inspired by a famous downtown legend, Jean-Michel Basquiat. His works and personal style are always the inspiration source of the fashion industry. And his signature pattern appears on the key items, including the oversized leather trench coat, blanket-style wool scarf and a new structure sense.

VETEMENTS is founded by Demna Gvasalia and Guram Gvasalia, a graduate of Royal Academy of Fine Arts. It witnesses the unruly street subculture. It is the benchmark of street brands and often copied by other brands. After Guram Gvasalla's departure, VETEMENTS makes a series of changes, retains its own style but begins to cooperate with other industries like Evian to keep energetic in the depressed market.

Massimo Giorgetti, the artistic director of MSGM, who is constantly looking for cultural inspiration from the past, is an unruly fun-goer. This theme is inspired by Gio Ponti's interior design of Milan architectures in the 1970s and the modernistic ceramic floor tiles. The concept of the collision and integration of classics and modernity is used to present the vivid and interesting design aesthetics. The classic bright color matching and bowknot of WSGM are used. The neat and clean silhouette replaces ruffle, with lively colors to be fresh and lovely. Various interior elements are used as patterns this time. The geometrics on the floor tiles are applied to the shirt, and classical rose pattern is used to the outerwear. Environmental protection is also advocated this time, like eco-friendly leather and faux woolskin, reflecting the designer's attention to the environmental protection.

In 2020, people no longer show their individuality through neutrality, but start to face up to women themselves and explore the original connotation of females. On Pre-Fall catwalk, knitwear tends to be mature and elegant. Many brands gradually get rid of the neutral and leisure style, and turn from blurring gender boundary towards exploring the original beauty of females. Knitwear reduces the large-scale textural feel and adds simple but exquisite designs. And designers apply rich and superior natural colors to knitwear.
