This bra was not my size. I don't have much to say about it outside of what I already said about this bra in the 42DD size: band runs firm, cups are narrow, and in the right size you may have problems if your tissue extends to your collarbone.
This bra was one of the early purchases when I was trying to sort out my bra size. It was way too small in the cups and narrow in the underwires, which I didn't understand when I bought it, but it hash eld up pretty well and gave a decent shape under clothes despite not fitting properly.
The cups come up pretty high and will require some upper fullness to fill. I think anyone with a shallowish upper breast shape (tissue extending to the collarbones) might have a little trouble with this bra cutting in in the proper size, but because I wore it several sizes too small my breasts forced the cups to buckle over which left them significantly more open on the top.
The band is firm for a 42, but is still too big for me.
