Current situation analysis: According to data from the Amazon platform in November 2023, sales of thermal underwear and tops have increased by 51.37% year-on-year since November, ranking first on the best-selling list. Meanwhile, the sales of thermal underwear sets have shown a significant decline, with a decline rate of 27.92%. (Note: The compound growth rate and year-on-year growth rate here reflect market demand.) Data conclusion: The demand for warm tops is significantly increasing, while the demand for set type warm underwear is decreasing, indicating that Amazon consumers are more inclined to purchase single tops rather than complete sets of warm underwear, and pay more attention to personalized and freely combined dressing forms.

Based on customer search interaction data and market research, data analysis was conducted on the hot search items and styles of women's sweaters in 2023. In terms of style design, the minimalist, fashionable and casual, and elegant Chinese style have received continuous attention from the market, and their popularity has not decreased. It is worth noting that the attention to young ladies' clothing has increased. In the single product data, apart from pullovers and cardigans, the attention of small cardigans in the market is gradually increasing, and the attention of dresses is also increasing.

The trading trend of men's double 11 sweaters in the past three years has shown a significant downward trend. From the transaction amount during the period of 10.30 to 11.05, it can be seen that the Double Eleven sales period entered on 10.30, and the transaction amount reached its highest during the period. During the period of 11.06 to 11.12, the trading trend showed a downward trend due to long pre-sale times, returns, actual consumer demand, and consumption downgrades.
