Clothing is e-commerce's largest and most dynamic category. Over 50% of consumers shop for apparel online, making it both attractive and competitive. With high volume, strong repeat purchases, and trend-driven demand, this guide walks you through starting an online clothing business step by step.
1. Niche and Target Audience
| Niche | Examples | Target | Competition |
|---|
| Women's casual | Dresses, blouses, pants, skirts | Women 18-45 | Very high |
| Men's casual | T-shirts, shirts, pants, jackets | Men 18-45 | High |
| Streetwear | Oversized, hoodies, joggers | 16-30, trend followers | Medium-High |

2. Sourcing Models

| Secondhand | Preloved, vintage, thrift | Zero production, trendy | Uncertain supply, one-of-a-kind |
