So now that we have female characters tanking in string bikini's and now men in wedding dresses, it's time to adopt an option a lot of other games have: Hide Glamour. Naturally troglodyte are going to assume it's because of the men in dresses. It's actually because it's breaks the theme and feel of it being a final fantasy game.
Sooooo... Female avatars can wear wedding dresses in dungeons and feel immersive and fine, but men can't... ... ... And I assume that female in tuxes (although heaven forbid they wear bikinis when that sort of style has been all the rage in RPGs since... RPGs were a thing practically).

-Sniffs at the air- Crikey! I think I smell a bit of sexism here! Y'all need to get over it. Right now, things are "exploding" because it's new. Once the hype cools down, people will go back to their usual glam. When weddings first became a thing, every female avatar and her sister were wearing wedding gown glams (at least on my old server). Now that guys get some more options, they're exploring them! Let them explore. People like you are exactly why they don't don't cater to the "female" audience because - regardless of gender/sex - they're too stuck on the stereotypes of what makes a man and what makes a woman. "Oh my god, that male character is showing his hips! CHANGE IT!" <-- What happened to male protagonist on one of the FF mobile games (his outfit did get changed).

Though I will say if you hate it so much, move servers... because I have not really seen an explosion of anything on my server (not saying I want someone like you on my server). Sure, everyone was wearing 2B's dress when it first came out. Within a week, almost no one wears it. It's like BLU explosion with BLUs everywhere! Crap happens, wait it out, get over it. Here's hoping they don't implement such a stupid system just because some people are soooo offended by men in dresses. News flash: 99% of healer gear are dresses. My regular bard attire (not a glam) is a freaking dress. Men had speedos/thong-like things even before 2B's tights came out, just as an FYI (and they're skimpier, too!). They're just uglier.

Immersion is not an excuse to be a bigot, considering we have so much crap that breaks immersion (e.g. Regalia, Yokai watch stuff, and more). Don't be a bigot.
