The Skinny on Slips

While flowing satin slips are great for loose-fitting dresses, when you're eyeing a slinky dress or fitted skirt, you need something with a bit more oomph. When it comes to slips with extreme slimming power, you'll want a tight-fitting number, preferably one that extends from just below the navel to mid thigh (make sure it's not longer than your skirt or dress though).

You May Want to Try: Slimplicity Half Slip

From the granddaddy (or grandmother) of all body shapers, this slip is from Spanx, by Sarah Blakely. The edges and seams on this skirt are laser cut, which creates a flat, even surface. No midriff lines here. Just one layer of compression fabric provides a trio of benefits: It flattens your stomach, thighs and hips to help you look sleek under skirts. This is a modern take on the traditional slip, since it cuts off at mid-stomach and isn't supported by shoulder straps. Size small to 3XL, $52 to $56.

You May Want to Try: Slimplicity Lingerie-Strap Slip

When you're going to sport a silhouette-hugging dress and the half slip just won't do, you'll need something that slims from mid thigh all the way to the bust line.

This slip alleviates the appearance of tummy bulge and troublesome love handles, while allowing you to customize with adjustable shoulder straps. It has darts and compression (76% nylon, 24% spandex) to compliment your shape. Size small to 3XL, $72 to $76.
