SOPHIE ALBOU'S Paul & Joe label is in easy, breezy mood for next summer. She's 16 years in now and her fashion vocabulary is well known - boyfriend shirts worn as dresses, loose striped jeans belted with handkerchiefs, cotton floral dresses to throw on over sexy cutaway swimsuits and loose weave crochet knits that fall off, just so, to show off a bronzed shoulder.
