It won’t be hard to slip into next season’s dresses with so many exposed zippers. Though his overall show got tepid reviews, Derek Lam was dead-on in incorporating visible zippers into most looks. Carlos Miele’s dark, ruched dresses came with a sexy zipper up the front. And Behnaz Sarafpour highlighted her external zippers all the more with bright yellow trim on an otherwise subdued gray dress. So come fall, remember to zip up.
