Disclaimer: I didn't buy this bra at Bravissimo, they don't have stores in my country, but it's this exact model and I needed to put a review somewhere because it's amazing and I really love Bravissimo, so I thought you girls would appreciate it!
I've never tried anything like this. It fits me perfectly, I feel like I'm not even wearing a bra and everything is supported and I can't feel the wires. I can always feel the wires at all times, but with this it is different, it's like it's made for my body.
When I first saw it, I was skeptical because the closing only had one hook. It just makes the back very open and cute, but I don't feel it lacks support at all. Perhaps if you're bigger than me it might, but the little criss-cross detail definitely adds support.
It also just feels kind of like a bralette, because it's not padded, which I personally love, but I know some people aren't as into.
I would size down a cup in this if you're between sizes; my size is generally 30F, I tried on other 30Fs the same day that fit, but with this I had to size down in the cup (30E purchased). The band is perfect though.
This is my dream bra. I'm so happy I found my perfect match, and I'll most likely order some more from Bravissimo in the other colours when I can afford it!
