Out of all the possible outfits in the world which show off a woman's body e.g, tight jeans, bodycon dress, short playsuit, bustier, the idea the only one that gives joy is a swimsuit seems a bit improbable.
And even if that were true- who's "destroying" this? Has anyone suggested there should be an MN version of say the Saudi morality police hitting women with sticks and making them cover up? You'd have a point if that were the case, but it isn't.
Funny really the only thread I've come across you was an S&B thread where you were complaining about a poster trying to shut down speech (she wasn't ,although you were). Now you are trying to control thoughts. Wear a bum baring costume if you like, but don't dictate that anyone seeing it can't think it looks awful.
