I’m a big fan of unlined bras because I already have a bigger chest. This bra definitely minimizes! I do wear non adhesive petals with it though as you may have headlight issues if you don’t. In terms of sizing, definitely go up at least 1 band size! I’m typically a 32DD and got the 34DD in this bra. (Even still, it’s a tad tight, so may have even been able to go up another band size.)
I love this bra because it has soft cups and is a front hook. The band seemed to run small and, since there isn’t a lot of cushion on the underwire, I ordered a size larger than usual. It might just be me but the straps rest higher on my shoulders than a regular bra and seem to cause some tension in those muscles. Overall, though, I’m quite happy with this bra.
