A Slimmer Silhouette
Even sylphlike models slip into shapewear to minimize bulges around the hips and waist. When temperatures are high, try Jockey's lightweight Shaper Brief ($19). Looking for a longer-term solution? A new device, Zeltiq's CoolSculpting, uses intense cold to destroy fat cells. CoolSculpting was approved by the FDA last fall for body contouring, and doctors are excited about the results. "It's fantastic for getting rid of pockets of localized fat, like love handles or muffin top," says Jeffrey Dover, MD, associate clinical professor of dermatology at Yale School of Medicine. The procedure is virtually painless; some patients experience aching in the treated area for a few days afterward, but most have no side effects. You'll see the maximum results after four months; more than one treatment may be necessary. (Cost: About $1,400 per treatment.)

Firm Knees
A long skirt can still allow for a sexy flash of your knees. If yours look more droopy than you'd like, tightening your quadriceps with squats might help. Are you convinced you want to tighten the skin around your knees? Then you'll have to visit a dermatologist. Some have seen noticeable results from Ulthera, a new device that heats the lower layers of the skin with ultrasound to spur collagen growth. One treatment should do, but it hurts—most patients take a prescription pain medication, like Percocet, and an antianxiety pill, like Valium. Thermage, which uses radiofrequency energy to grow new collagen, can also tighten loose skin on the knees and is less painful than Ulthera. (Cost for either: At least $600.) Both techniques are most effective in the early stages of sagging.
