I need more support and keep finding ones labelled light support. I am a 38/40C right now and don't want to spend a lot because I will likely shrink down to a 36C. It is uncomfortable to run and do jumping jacks now. Any suggestions? Thanks!

I really love the Fiona sports bra from Moving Comfort. I have like four of them, actually. The straps are quite adjustable on the front with a comfortable velcro system, it's got a hook and eye closure which is very secure and molded cups. No underwire or anything but I find them incredibly supportive.

They're also on sale a lot, so if you google them you're sure to find a pretty great deal! Good luck!
