I was warned that Curvy Kate bras typically don't work for full-on-bottom breasts, but I wanted to try one to see for myself. I was not shocked that there was a lot of excess material at the top of the cup. There's also too much material at the outsides of the cups (under my arms). It's not that the cup goes back too far (I do have wide roots) but that there's just extra material, like the bra was expecting me to have twice the amount of breast tissue on this area of my body. It might be worth trying the 34E (same band, one cup size smaller).

I wouldn't completely write off Curvy Kate bras. Sometimes fit can be off, especially if you get hold of older styles, and sizing doesn't always correlate to what you'd expect a UK size to be, but there are worthwhile bras for bottom heavy boobs.
Most recently I faired really well with the black/violet Bardot sheer cup. I had to size up from my usual 30GG to a 30H but it fits so well.
