And how many do you go through in a year?
I've had three since january/coming out. An underworks tri-top, which I wore every day for four or five months (four or five months of not being able to breathe >~<). Got me completely flat to begin with, but by three-ish months it wasn't doing much more than a sports bra would (plus the classic uniboob effect).
Then I got two GC2B tri-tops - perfect for my body shape, got me flatter than I thought possible to begin with, but having worn them everyday for five months (so probably 2.5 months worth of continuous use on each of them) I'm back to the sports bra/uniboob effect. And still not a fan.
Happily, winter is coming so I can hide it with layers, but I can see myself replacing them come the spring. Money ;-;
Just wanted to hear some other guys/transmasc people's experiences. Thanks in advance for any responses, and I wish you all a fabulous weekend :3
