Hi Yeli,
I'm not familiar w/ that vendor, but may I suggest an alternative?
Go to
The Belly Dance Store and click on "Affordable Costumes". She has a set called the Great Basic that's just that- an affordable, great basic set- in lots of colors/sizes. Even if you look under "Designer Costumes", she has a lot of affordable choices.
Bellydancewithk.com also has a few available in the $200 range. But they get snatched up quick!
These are known and trusted costume vendors (I'm sure other bhuzzers will agree). You wouldn't have to take a risk on a random ebay vendor.
