Vassarette Women's Comfortably Smooth Slip Short Panty
I used to wear Spanx shorts under my dresses to prevent chafing until I realised it was too much of a pain in the ass to keep pulling them up to my bra line. Enter the Vassarette Women's Comfortably Smooth Slip Short Panty ($6-$36), which is easier to put on (and happens to look a lot cuter, too).
