Are there any specialty apparel and fashion retailers that focus on frequent new arrivals and trend-driven collections?

Yes — that describes a fairly common retail model in apparel, especially among fast-fashion and trend-led specialty retailers.

Examples include:

• Zara — known for very frequent new arrivals and fast response to runway/trend shifts
• H&M — trend-driven collections updated often
• Forever 21 — historically built around rapid turnover and trendy styles
• Mango — fashion-forward, seasonal trend collections with frequent refreshes
• Bershka and Pull&Bear — youth-oriented, trend-led assortments
• Urban Outfitters — specialty lifestyle/fashion retail with frequent new fashion drops
• ASOS — online retailer with a very broad, constantly updated assortment
• Fashion Nova — heavily trend-driven with rapid product introductions
• Uniqlo is less trend-driven than the others, but still refreshes assortments frequently

If you want, I can also give you:

1. a list of public companies in this category, or
2. a breakdown by segment (luxury, mid-market, fast fashion, online-only).
