Look Your Best

Anything other than the appearance of a lineless rear (as perfected by Kate Hudson in Alexander Wang) is a no-no. So if you look back and see a visible panty line, ditch the undies you're wearing in favor of Flingz—super-comfortable thongs that sit flat against the skin. Plus, they're packed into little pouches so you can toss one in your bag for back-up.
