On their last visit, Anna and Kristina (authors and TV hosts who are known as "The Shopping Bags") shared their tips on choosing the right bra in order to get just the right amount of boost up top. They're back, this time to talk about "the lower deck," as Rachal puts it. What's the key factor in choosing the right underwear? "The goal is to get that smooth look under the clingy dresses or jeans -- getting rid of the bumps," Kristina explains.
Thongs Some people complain that thong underwear is uncomfortable to wear. But for those who do like them, you want to make sure you eyeball the thong part in the back. Though you might think more is better, if it's too wide and the seams are too thick, then it's not going to feel very good. "Thinner is better," the ladies conclude.

"So you're telling me you need to get the tushy floss?" asks Rachael, who proudly admits that she prefers "coverage on the cheeks!"

The "Slingshot Effect" When your undies peak out of those low-rise jeans that's never a good look.To avoid the "slingshot effect," go for low-rise panties. Hold up the underwear against you to get a feel for the rise. Also, you can stack several pairs of underwear on top of each other and look for the lowest rise.

Getting a Smooth Look Microfiber is a great option in underwear because it's a very thin fabric and hides well under clothing. Polyester or nylon are other good choices. Cotton, on the other hand, tends to shrink and may not wear well over the years.

Pantyhose and Tights The key thing to look for is the "denier count." This indicates the thickness of the fabric -- the higher the denier count, the thicker the stocking.

For regular day wear, you should choose pantyhose with a 20 denier count. Tights should be above a 40 denier count.

The other number to look for is the Lycra number, which measures stretchiness and durability. A good lycra number for everyday hose is about 12 percent, which will give you some sheerness with durability.

You want to avoid a "muffin top" look with tights. This happens when the control top band is too thin and it rolls down.
For a smoother line, get a "zero waistband." It's also called a wide waistband because the band is wider and flatter, giving you a look like you've done 9,000 sit-ups!
