There was a time when the bottom of the costumes was designed to look like that! I think it was when high cut swimming togs etc were all the rage too.In all honesty the only cringing I have ever done with figure skating costumes is (and I don't know if they were made by ppl inexperienced figure skating dress makers or wrong material)when the ladies leave their butt cheeks hanging out there and wedgies galore. There seems to be a special method to fix the prob. but a lot of skater's costume makers obviously don't know the secret.
