These things can get really hot so maybe just wear a light shirt on top (like the formal button up type as it will allow some air in through the gaps between the buttons) Good to wear in the winter to warm up easier but in the summer it probably wouldnt be too fun
I just got my first one today for the sake of trying one, underworks 997. Heard it was really good even for big chests but unfortunately not doing too much for me. Slightly flatter compared to not wearing it but still far from being flat (I know cisguys arent completely flat but Im even far off being that) Guess nothing can really work when you're this bad. All I can do in the meantime before surgery though. Its a slight improvement but not sure the discomfort and restricted movement is really worth it. Its fine on my front, no breathing issues what so ever or any tightness/pain. Its only really tight on my back, seems to be tightening in around my waist at the back. Thats all that hurts but is pretty annoying. Dont know if I'll wear this much or not since its not much of an effect but being this bad I kinda expected that. Worth a try anyway I guess. Might tri-top or a different one work better or is there just no point trying? Got a waist belt too to try make my waist look better, alot of my unwanted weight is around there so this helps shove it down a bit til I can lose it. Came extremely quickly though, ordered it on Tuesday from the US and it arrived here on Thursday (Im in the UK) Didnt expect it could even get here this fast lol
