If there's one thing that's already in full bloom, it's the latest batch of designer collaborations to crop up for Spring. From the high-low partnerships to the unexpected duos, to the matchups that continue to reinvent the wheel (hello, Kenzo x Vans!), this season's most exciting collaborations promise to supply us with our fair share of Spring-perfect pieces. Think bold prints à la Derek Lam for Kohl's DesigNation, cool-girl heels courtesy of Preen for Aldo Rise, and slick denim staples from Kate Bosworth's stylist Cher Coulter and AG Jeans. All this - plus 15 more designer collaborations - make the transition to Spring's lighter, brighter wares a much more interesting shopping affair. Click on to see what we're excited to get our hands on.
