I've been in love with this costume for months now but kept putting off buying it... I actually found it at WalMart the other day & it was only $35 so I bought it. Mine didn't come with the gloves unfortunately - but that does not reflect the content of this costume here.
But I have to agree with the other review, you definitely need double-sided tape. I bought a Medium (8-10) although some places it is listed as x-small, small & standard. I would guess that my medium would = standard. The bottom part fits fine, but the top isn't wide enough for my... 'girls', for lack of a better word. I too, am only a B cup but once you have the front v-plunge situated, you're popping out in the back. I think it's just that the shoulder straps cut too closely.
Unfortunately, my Halloween plans fell through so I really don't have anywhere to wear this, but I know if I had just a bit of tape to stick to each side of the top part, it would be fine. I still plan on keeping the costume... you never know!!
It's a great costume, really pretty color blue, and looks just like Gaga's suit. Just be prepared to have to tape yourself in if your a somewhat modest person. I usually don't go for the super-sexy look except for Halloween (and of course, the Gaga show I went to) and this isn't TOO bad - unless a 'girl' makes an appearance - lets hope that doesn't happen... Overall I would recommend buying it :)
