I'm in the ittybittytitty committee...and strapless dresses can be a huge problem. They're almost always too big for me in the top and I HATE worrying about whether it's going to slide down or not. My two solutions: fashion tape and alterations. Getting the dress altered to fit (and always get a correct fit on the bra, then wear that exact bra to the appointment with the tailor) is the best option and I have to do that for just about every formal dress I wear. But when there isn't enough time (or money) fashion tape can help everything stay in place.

If the dress is fully lined I've bought a size smaller before and gone braless. It can occasionally be a little uncomfortable but as long as you can't tell...it stays up better (at least for me...and if the dress still looks like it fits in a size smaller than I'd usually buy). But this is only if you are a small enough cup size to not really need the support (the ONLY advantage to having small boobies, sigh) and if you've made SURE there's no nippage. Because that would not do at a recruitment party...at all.

So if you find the perfect dress and it's strapless try to make sure you have enough time and money to get it altered to fit you like a glove, or at least have some fashion tape and a bra that fits correctly, and you'll be ok.
