Very quick review - I can't measure the band length because the band is attached inside the tankini. The band seems to be TTS or a little tight for a 34 band, and thus is too large for me (32GG is my best UK size).
The cups are narrow, fairly projected, and quite low cut. I am pretty happy with the fit of the bust portion, though the top of the gore pushes out above where the underwires end.
The stomach portion is too tight for me to be comfortable wearing it. I am a US 12 dress size (UK 16).
Quickie initial impression: Fits. Almost. Front over boobs is a bit snug. Front over belly is a bit snug. Back is still too long. Bottoms actually almost fit me, too. If I lose about 5-10 more pounds, I think it will be perfect.
I've always wanted a bandeau bikini top but had never found one that fits my boobs and is supportive enough. When I saw the Veronica Badeau by Panache, I fell in love instantly! I usually wear a 32GG, but the biggest cup size for this style is G and so I decided to try a 34G and alter the band if necessary. It wasn't. The band is very tight for a 34 and fits me perfectly, but this is something to keep in mind when choosing which size to order. The cups feel true to size and again, a great fit; they're moulded and the shape they create is amazing, perfectly rounded and uplifted. I love the Veronica Bandeau! It's gorgeous, sexy, supportive (thumb up for underwired strapless bikini tops) but very comfortable, well-made. Only complaint, the size range; I'm sure many GG+ ladies would love this bikini.
