For House of Holland's Fall '13 collection, designer Henry Holland kept things sleek and fun, yet perfectly polished. The rocker-cool Brit offered up ladylike geometric-print day dresses, metallic trench coats, and slouchy knits with a decidedly psychedelic '60s vibe. In the way of accessories, Holland didn't disappoint; his retro go-go girl will be clad in oversize cat-eye sunglasses, wide waist belts, and best of all, jewel-encrusted leather baseball caps. We can't wait to see the pieces sported on the street by Holland's brood of celebrity fans, including style setters like Poppy Delevingne and Alexa Chung. Click through now to see our curated list of the 10 coolest looks from House of Holland's Fall 2013 runway show.
