It looks I'll again be in the middle, opinon-wise, as is my wont.
We live in times when athletic attire is stylish, practical, beautiful and comfortable, without being garish or looking dated.
But who decides what classifies as garish and dated? Many like what someone else considers ghastly, and vice versa. Maybe the skaters themselves like those costumes, since most wear adorned ones and are willing to pay for them. I refuse to believe they're all brainwashed into wearing them by their coaches, judges, and the audience.
The sooner it becomes acceptable in figure skating competitions, the better imo.
But it is, isn't it? I recall Kostner wearing a loosely fitting lime green unitard that looked quite comfortable, years ago. AFAIK, noone docked points from her for it. If more skaters don't wear unitards, I suppose they have their reasons for that, and that's okay and it's their right to choose whatever they want to wear.
If a woman wants to wear leggings and a t-shirt it should be allowed and she shouldn't be penalised for it, but if someone wears something she looks great in, the cut is flattering, it's colourful and exciting then if she receives inflated marks then that's how it should be. She went that extra length to make an impression on the audience. Male figure skating I think is different that is much more an athletic endeavour and jump show, female figure skating from a mature figure skating can be something sensual.
I disagree with the double standards here. Both men and women should IMO strive for both artistry and athleticism. For me, jumps alone, or music+looks alone, don't make FS. I don't want male skating pursue hard jumps and little more (until their knees, hips and ankles are done in in one Olympic season), and female skating focus on looks or, heaven forbid, on being 'sensual' for the judges and audience's eyes; that's just creepy and I hope I misunderstood your comment.
One thing that can't disappear fast enough is the necessity for skaters (especially the female ones) to come to*practice* wearing full make-up and all that. I vividly recall a well-known skater complaining about it, though I cannot recall who - maybe someone remembers? The skater was saying all girls had to get up incredibly early to get their makeup done just for practice, and that's very wrong.
