I'm normally a 30FF, but I read somewhere that Gossard had slightly off sizing. This one mostly fits, but the wires can be a bit high.
It's a great bra, because the lace doesn't go to the very top of the cup, thus avoiding odd wrinkling under clothes. I fit into it well, except the cups flex at the top when I bend over, but spring back in the right place.
Nice tight fitting band, but sized smaller in the cups then other UK sized bras. Pretty bra with some push up. No padded cookies. The lace overlay covers the seams of the three part cups, but this all shows through a T-shirt.
