Your tummy has the capacity to expand to the size of six baseballs, which makes it super easy to overeat. Next party, wear skinny jeans or a tight mini and a fitted top, and if you own Spanx, slap it on, too! These anti-expansion pieces are a great way to keep your stretchable stomach from, well, stretching. Pair your slimming outfit with a clutch rather than a strappy purse; this way, if you have a drink in one hand and your clutch in the other, you can't dig into the chili cheese nachos.
