Anecdotally when I was younger and mine were coming in wearing something over them didn't change how big they got even though I was wearing really tight sports attire- but just keep in mind that when they do get bigger any collected sweat from your underboob can lead to rashes and general discomfort, so if you feel more comfortable wearing something, just make sure to wash the area often and make sure the skin is dry before wearing more clothing. I also put a little bit of baby powder underneath to keep myself feeling comfy. Hope this helps!
I don't want to doxx myself too much but when I went to go change my name on my CRBA (consular report of birth abroad, it's my birth certificate) I didn't realize that there was a listing for sex on it too- so now I have to get that changed even though all my other ID paperwork has the right gender marker and name on them. :(
I'm stuck in Texas, would anybody happen to know how difficult it is nowadays to just like... Get that changed real quickly? I just need the proof that my gender marker has been corrected so I can get that one damn document fixed.
