I’ve had such an annoying (& expensive) time with sports bras! I bought a Macom and a 34e Asda one at first but straight after surgery the Asda one was way too small so I bought a bigger size in it which then was too big when the swelling went down, so I bought another Macom.
I found with the macoms that they didn’t fit me properly under my boobs so it caused so much irritation I felt like crying every time I did any movement! So now I’ve bought two from m&s which are the best and so comfy. Their tight but not really tight, tbh after the soreness from the Macom bras being a little loose I’d definitely say the tighter the better xx
