I’ve got the MYA bra, mine is a medium and honestly I find it so uncomfortable. Can’t speak for everyone but the band is very thin so it folds easily, which was fine when I was covered in tape but as soon as that came off it cut into my stitches. I’m not fat, but when I sit down my boobs do rest on my belly, if I’m stood up the band sits flat and it’s pretty comfortable, tried to wear it to bed tonight though and had to switch to a sports bra I’ve bought because it hurts too much.
If you’re buying their bras, opt for a larger size as it’s adjustable anyway 🙂 better to be safe than sorry as when it folds, it’s pretty painful
