This season's fashion love story? The tunic sweater and the legging. It's everywhere, but thankfully in so many iterations it never gets boring. The reason for all the fuss? Cozy, comfortable and cute. And the long, belted cardigan from Ava Knits has such gorgeous texture with all those ribs falling on the bias over the hips for a fabulous slimming effect—and the sleeve creates gorgeous shoulder width. Meanwhile the Shape FX leggings flare nicely at the bottom, which is good news for an A because that pulls the hipline into proportion. Sweater tunics and leggings—together forever.
