Wonderful!! You really look like Cammy! I must say I like her normal Delta-Red-Costume more and the costume she wears in the mountains when she fights against Juri in the SSF 4 OVA too, but you look so beautiful and cute in her Shadoloo-uniform... awesome cosplay! I`m really impressed!
They're just regular dance tights actually, a friend of mine luckily had an extra pair I borrowed that weekend but you can get them from any dancewear store. Layering them really seems to help with opacity if that's what you're looking for!
