Designer Arlene Guerra is a crafty chick, adding a dash of this and that to her to her re-worked vintage jewelry pieces. Her collection, aptly called Pretty Young Thing, is for the woman who comfortably wears1950s siren dresses with patterned 1980s-style flats. And her pieces are fun, deliciously egging you on to subscribe to a mischievous lifestyle. Arlene Guerra was inspired by childlike costumery for her Spring 2009 Pretty Young Thing jewelry collection. The pieces, as you might expect, are an aesthetic mix of young vibrance and mature confidence.
