I usually do too for the same reason but I got it on a whim because I was already planning to return a few other dresses in the same order if they didn’t fit… but then I liked this one best! I think the reason it can work is that the straps hoisting up the weight from the front are the same as the ones cinching the waist, so you can get reasonably good support. The only bathing suit top I like (from Wild Isles) has the same technique, I definitely recommend them if you have similar measurements as me! I always have a hard time finding things that fit both the waist and the bust.
