hello โค๏ธ
my son is a senior in high school and will be attending prom with his boyfriend in about 3 months. he hasn't decided what exactly he's going to wear, but just in case it's a tux or a suit, I'm trying to get my ducks in a row because idk where to even begin. ๐คฆ
searching "rent a tux near me" gets me all kinds of cis-man focused stuff, adding "trans man" onto the end didn't get better results. I'm sure there are all kinds of considerations to keep in mind, but idk the first thing about getting a tux for anyone at all, let alone a person with a different body shape than Average Dude.
I might be over-complicating this and worrying too much (haha me? ๐ ๐ never!) please let me know if that's the case. it would be a huge relief!
I know we need to start with measurements; I'm fairly confident about taking them, since I've previously successfully measured him, my husband, and myself.
after that, I'm totally lost. his body shape is becoming more blocky and less curvy, but he's still got a little bit of hip that seems like it might be difficult to fit in suit pants. he has binders that he finds comfortable, so I think shirts and jackets might not be too difficult to fit, but heat might be an issue? he gets grumpy when he's too hot, just like his mom ๐ฅฐ
we live in rural Ohio, so I don't feel comfortable taking him to a random rental place; most of the time, people are nice to us, but I don't want to risk it for prom. we can drive about 2 hours to get to Columbus, OH, which has a pretty large queer community and probably has a safer place to go for fitting than anywhere closer.
all of your thoughts, directions, suggestions, advice, encouragement, reprimands, and jokes are welcome 
thank you.
Honestly buy one.
You can probably even cop one cheap at a second hand shop, they get worn once a year at most so are usually in pretty good shape. Even new it'll pay for itself in two uses. Used it might even be cheaper than a rental and you can branch out into colors besides black. Navy always looks great, and of course a white jacket is peak performance
Don't overthink it, find one that sort of fits then if you feel generous have it tailored. Black dress shoes are fine (shine them up!) and for the love of God and all that is holy get a proper bow tie and google how to tie it. Clip ons look ridiculous and an untied bow tie is a party accessory must. Cumberbunds or whatever the hell they're called are hella dated, suspenders all the way. Top it off with a pocket square. He will look dapper!
