>> The idea behind Zac Posen's Resort 2012 collection? American Royalty. "It's about how to be dressed up and poised, but still cool; Patti Smith in a gown and Penelope Tree in a trench," says Posen. The way Posen plays with silhouettes is a study in contrasts: a soft, buttercup-printed chiffon dress is gathered into bodice-hugging seams, only to be let loose in a flurry of ruffles at the hip; a peplum waistcoat with a second-skin fit gets a hit of volume at the sleeves with tiers of unfinished chiffon ribbons. But this is still classic Zac — with lots of show-stopping gowns on offer. The stand-out number? A 720-yard, hand-dyed vermillion confection with a swirling, mermaid train.
