By 2025, bell-bottoms unexpectedly became a phenomenon in the US women’s fashion market.
From the Super Bowl to TikTok feeds, this trouser style, once popular in the 1970s, has made a strong comeback, driven by a trifecta of cultural symbolism, social media influence, and product upgrades.

Celebrity influence has become the catalyst for the bell-bottom trend.
At the 2025 Super Bowl halftime show, rapper Kendrick Lamar performed in a pair of $1,300 flared jeans. Their “narrow at the top, wide at the bottom” silhouette was highlighted in The New York Times, instantly setting the fashion world on fire.
The appeal of celebrity-inspired styles quickly spread, with Hollywood actresses and influencers sporting them, transforming flares from a retro staple into an annual must-have. Data from the Los Angeles boutique Fashion Hub shows that after the Super Bowl in February, in-store sales of flared pants surged 210%, with celebrity-inspired styles accounting for over 60% of the total.

TikTok’s viral reach has accelerated the trend.
The #FlarePantsTrend hashtag on the platform has exceeded 5 billion views, with users spontaneously digging out retro flared pants and filming outfit videos. Expert reviews have become a powerful tool for promoting this trend.
British blogger Grace’s scathing review unexpectedly boosted sales, stating that the pants are “flattering and comfortable, and they look longer with sneakers than high heels.” The comments section was flooded with requests for links, driving sales of the affordable flared pants she recommended 30-fold in a week.
This user-generated content has rapidly penetrated the youth demographic, with consumers aged 18-35 contributing 75% of US flared pants sales.

Product upgrades precisely meet modern needs.
American consumers increasingly prioritize “comfort and style.” New flared pants are made of high-stretch fabric (some with up to 15% spandex), addressing the tightness and restricted movement of traditional styles while still maintaining the benefits of flattering leg contours.

Guangzhou brand Katch Me’s high-waisted, slightly flared pants, featuring a “stretchy, non-tight fit” and a tapered hem, have become one of the hottest trends on TikTok Shop in the UK, with monthly sales exceeding 100,000 units, 80% of which are from the US market.

Supply chain responsiveness has further fueled the trend.
US factories typically have a delivery cycle of 30-45 days, making it difficult to keep up with the rapid pace of fashion trends. The “small order, quick response” model of Chinese factories has become a key driver of this trend. Chenghai Women’s Clothing Factory, which specializes in OEM production of women’s clothing, is a prime example of this model. As a company long focused on flared pants, the factory currently boasts a stable daily production capacity of 5,000 pairs, covering mainstream styles in the US market, including flared, wide-leg, and vintage-inspired styles. The factory can handle both small-batch custom orders with a minimum order of 300 pieces and bulk purchases exceeding 10,000 pieces. Sample production and delivery can be completed in as little as 10-15 days, perfectly meeting the demands of US brands for rapid order fulfillment and time-sensitive delivery.

Recently, driven by the US craze, the factory’s share of US orders has increased from 15% to 38%. Many TikTok e-commerce sellers are seeing their flared pants, custom-designed with their own logos, sell out instantly upon listing.

The collision of retro fashion and pragmatism has led to a dramatic transformation of flared pants in the US market in 2025. The supply chain strength exemplified by Chenghai Women’s Apparel Factory is helping to transform the trend from a buzzword into market sales. The factory has now opened a dedicated channel for US customers. Brands seeking custom-made women’s flared pants can directly access a library of patterns, fabric samples, and quick quotes, making it easy to capitalize on this wave of American fashion trends.
