Visit BellydanceSuperpower.com to purchase my own creation: "I Bellydance. What's your superpower?" shirt. XL only.
Some of my favorite sources for bellydance supplies:
Bellydance.com (operated by Hollywood Music Center) - I buy my light-weight square sequin hipscarves here.
Scheherezade Imports - Lucy is the best! Her warehouse is just outside of Richmond and she vends at many events on the East Coast. She stocks excellent beaded fringe, a wide assortment of hipscarves, various accessories, and some beautiful costumes.
Dahlal Internationale - Full costumes, accessories, music, and more. They are located in Missouri, but travel to several events across the USA.
The Belly Dance Store - They stock an amazing (and overwhelming!) amount of costumes, ranging from simple student sets to glamorous professional designer costumes. Located in Baltimore, Maryland, but they ship internationally.
L Rose Designs - Great custom made skirts and tops. Many items are ideal for hafla performances. Their coordinated sets can't be beat for making troupes look cohesive!
