I'm not trawling through 17 pages of this nasty thread to c&p examples, but we all know that's exactly what's being said all over and the comparison to football shirts is utterly laughable. Starting a thread purely to judge women for dressing in a way that you don't like is right up there with it.
Wear what you like/do what you like is a very liberal feminist approach that ignores the inherent and enduring power structures in society.
This is just a pompous variation of that old chestnut: that if women say they do if because they like it, and men say they do it in order to please men, we decide to give the dudes the casting vote and ignore and insult the women.
Of all the terrible societies history has seen, none of them suffered an absolute moral collapse because a small percentage of women chose to dress in a way that a certain kind of person found offensive and wanted to judge, as if it's a moral issue. However, plenty of them revolved around the kind of ridiculous shaming of any woman who chose to express herself and her sexuality. And who thought what the men said about it outweighed what she said about it.
The price of freedom is that some people will do things you don't like. If the worst of it is a bit of swimwear, we're doing very well. You can generally see full bum outlines under swimming costumes anyway if you're the kind of person to take a keen interest, like many posters are.
