Obviously, sweaters have always been winter's go-to, but this season sweaters are made of thick knits and are oversized as ever. Whether they're crew necked, turtlenecked, long sleeved, batwing sleeved, or otherwise stylized, they'll work. Forget just wearing them with skinny jeans or leggings and boots (which obviously works!), sweaters over a-line and pencil skirts, boyfriend jeans, maxi dresses, leather leggings, layered over shirts, under leather jackets and more are the preferred methods of pairing for these heavy winter items. You don't even have to give them up when dressing up. The street stylers (and one model) above got the look exactly right.
Cheap options are all over if you want to stock up, but pricier (and, frankly, better quality) choices are available, too if you want to be sparing with your collection. Get started with some great choices at Uniqlo, H&M, Joe Fresh, J.Crew, Club Monaco and ASOS. But they really are everywhere right now, so browsing around will offer much success. I just picked up this one, this one and this one over the weekend (I know, I went a little crazy).
