With all the things you must decide each day--sushi or chinese, yoga or pilates, decaf or regular...not to mention the small miracles you perform by juggling work, home, school, boyfriend and whatever else may be on your plate--wouldn't it be nice to make one less decision? It's true, two-piece sets and pre-determined combinations (a.k.a. outfits) can get a bad rep. Sometimes, though, it's nice to have a solid go-to option, other than your favorite jeans and white tee, to throw on with minimal thought. A business meeting can call for more than denim but less than a suit. Skirtsets are an equally efficient and pretty option that will impress and still look effortless. Twinsets and coordinates are another a great way to look put together without spending too much time to wardrobe decisions. Because really, your time should be devoted to other, more important dilemmas. Like which nail polish to use, for example.
