If you want to go with the clothes you have, take a look at some of the brands you wear. You'll want to go to the manufacturers website and contact them about being a wholesaler.

If you're looking to expand, I would suggest that you look to indie clothing designers. You can find some ideas for designers at http://modcloth.com. But generally, you find who you want to use and then ask them about wholesale pricing. Same for jewelry and shoes.

Here are some ideas for jewelry and other things:

http://dougdsouzajewelry.com (love the world peace pendant)
http://thecuftlynx.com (for men)
http://thegemstonegiant.com
http://jewelrybydezign.com
http://theresajeankibby.com (unique rosaries)
http://treasuresbynina.com
http://triplewillowgiftgallery.com (love the beaded glasses)
http://uniquebears.com (not pricey at all when you consider they're one of a kind)
http://candlebowls.com (really awesome candle bowls)
http://vintagegirldesigns.com (cute cards)

Keep in mind that you generally will not be able to get the wholesale pricing list until you have a tax id number. Also, some of the companies will require you to spend a certain amount of money to get the wholesale discount.

Good luck!
