1. Undergarments can drastically change the look of a dress.
You already know that wearing a strapless bra or a regular one with clear straps is non-negotiable. Even so, I’d recommend getting your measurements taken before you start this process, especially if you've lost weight recently, like I did. When I tried on the winning dress for the very first time, my bust looked...off. The culprit: Undergarments one cup size too small and three inches too big around the waist. Armed with my correct size, I slipped on the dress again—it's amazing what a difference a few inches can make.
