I bought the M&S zip front sports bra but I found that at night at the seams dig into my back. So I got a larger size and I still have the same problem! I can’t find a single sports bra that I’m comfy in and I worry all the time that they ride up and dig into the bottom I f my boobs! I’m only on day 2 of wearing sorts bras and they seem to hurt and million times more than the strapping now 🙁 Have any of you found this? Xx
