DD has a small frame and 30E bust according to boob or bust. She generally finds 32DD are more comfortable (and easier to find in shops) as she hasn’t got much fat around her middle but I think 30E would be better for a sports bra. As she is short with a smallish distance from shoulders to bust she needs to be able to tighten the straps but sports bras don’t usually have much leeway. Can anyone recommend a 30E sports bra?
