What: Lululemon yoga pants
Why: You never know who you're going to meet at the gym. Why not look your best in workout wear that has function and fashion? Lululemon fans rave about the rump lift of the groove pants — a "Wonderbra for butts"–and tall ladies will love that these modern miracles come in both regular and tall. Just don't let anyone catch you admiring your rear in the mirror during Chataranga.
