Your best choice is high waist compression underwear that will gently tuck your tummy and smooth your curves, giving you a va-va-voom silhouette. If you are wearing a dreamy slip gown, then you will have to deal with more of a silky fabric that tends to cling. This type of dress is all about creating a streamlined look by wearing seamless shapewear. We just love butt lifter shorts for these kinds of dresses, especially if they have a tummy compressing panel that is completely invisible under the sheer, silky fabric.
