Basically that, really. I exercise 2-3 times a week and have started running again and have noticed just how awful my sports bras are. I have two of the same Nike bra which has a hook-and-eye fastening at the back, rather than pulling over the head.
I’m a size 8-10 (although probably more like a 10 at the moment) and wear a 32E, although I’m expecting to be a DD when I get measured again.
Where are your best sports bras from?
