Poser Pants: It's a mystery, but women's yoga pants by Lululemon Athletica are somehow -- magically -- universally flattering. The Reverse Groove style has clean lines and a chafe-free cut, and uses moisture-wicking fabric. Plus, it's reversible. (Try-on tip: A temporary Lululemon store with limited hours and selection is slated to open on Boylston Street in May. Watch lululemon.com for details.) $84 at 877-263-9300
