Wondering what to wear this weekend? I've got you covered. This Derek Lam 10 Crosby top is a must-have basic this season. I've shown you how to wear it two ways but the options are truly endless. Not just for spring and summer, you can wear it later layered under a blazer for fall. I especially love this top with our J. Brand leather skinny jeans and Chelsea Paris snakeskin stiletto sandals but think it is equally cool and casual with boyfriend jeans and sneakers. See below for details and links for all these items and other additional options.
