I tried my second size in this bra today - exchange from 28J to 30J - and I can confidently say that this bra is a terrible shape for my shape and size. I normally wear a 28HH in Bravissimo, and have a forward, full/round and close-together bust. There is no space in this bra for my upper bust, and the compression drags my full upper bust downwards in a weird slope. The apex of the cups are very low, for me on the underside of my bust. The straps are very long, and can't be tightened enough for the bra to be supportive for me. It's would have been good that the front of the bra is high if the straps could have been tightened. The cut at the armpits are too painfully high and cut into my arms. The band is very, very tight at the back, loose at the front. This 30J band is overall more like a 27-band. The 30J cup is more like a 28H in volume.
I think this bra might work if you have less volume or fuller-on-bottom bust shape, with shallow top bust.
