Very form fitting. You will need the proper undergarments. I loved it.

I ordered a small it fits perfect not too big not too small. It's not see through although just like any other clothes (leggings) if you buy them too small you will stretch the material and you will be able to see through it. The length above my knees is about 4 inches, it's perfect. The stitching seems legit, in my opinion it was a good bargain.
