NEVER WORN! I purchased the wrong size for a wedding the day before. Extremely well made. The boning pulls everything in. The mesh makes it so easy to move around and breathe. Extra bonus - you don’t need to take them off to use the restroom. This genius underlayer is guaranteed not to roll up or down, no matter how you move, thanks to targeted X-compression that sculpts without squeezing.
