Olivier Rousteing is the new designer at Balmain, but only in a manner of speaking. The 25-year-old Frenchman has already put in two & a half years at the house, working as an assistant to Christophe Decarnin just as Balmain burst to recognition in Paris with its superluxe rocker-girl aesthetic comprised of glitter pelmet dresses, skinny jeans, & tennis ball-shouldered jackets. Resort is the first season in which Rousteing has had control of the collection since Decarnins exit earlier in the year, & by the looks of the " Elvis in Vegas" theme hes worked, the precociously experienced designer (he has a pedigree that stretches back to working with Roberto Cavalli in Italy) is set on preserving continuity.
