Rectangular silk belly dance veil by Fairy Cove Silks. This is the classic shape for a belly dance veil. If you've borrowed my veils in class, they have most likely been the same size, weight, and shape as this one. 5mm, 3.5 yards.
Egyptian hip scarves are more heavily beaded which gives them a nice, lush weight when you dance. It also supports the artisans in Egypt, where this dance originates. Dahlal.com always has a great selection.
The Saroyan professional series is the size that I usually play. they are lighter weight than the Turquoise Int'l ones with great tone. This website also allows you to hear the tone so you can choose what you like. About $50 but they'll last you a lifetime.
All the hip scarves! I really like these kinds of hip scarves. They are sparkly, light weight, layer-able for costuming, and relatively inexpensive. I sometimes have these kinds for sale in class for around $10 or $15, but dahlal.com has them all the time if you really want one RIGHT NOW! Shake it!
Awesome resource for bellydance jewelry & accessories (both finished & DIY components). I own a lot of jewelry from them. I haven't bought any of the costume/bras/pants/clothing, but I've heard they're very high-quality.
