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 these 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.
