This bra is very comfortable, but I couldn't even come close to filling out the lace on top. I think most 30Ds would find it difficult. This might be a better fit on someone closer to a 30DD/E or someone who is very full on top.
Cups are WAY too big at the top. I only fill them about half way. Had thought initially that it was only the lace that was baggy and loose but upon second tru on realized that the cup itself may be too deep?
