How do I find good wholesalers for women's contemporary clothing up to size 5x?
Is there a market for this type of clothing? If not, move on to something else. If so, and if it is truly a niche worth pursuing, you may need to go to a manufacturer and design your own line of private-label items.
Then you can become the wholesaler to retail outlets or a direct retailer with a unique private-label brand.
All the best.
