New York-based designer Rosie Assoulin worked for the likes of legendary couturiers Oscar de la Renta and Alber Elbaz before launching her own luxury label in 2014. The designer's eponymous brand epitomises wearable, contemporary couture, characterised by sculptural ready-to-wear pieces in bright hues. Combining a love of colour with a penchant for vintage glamour, Assoulin specialises in elegant evening wear in statement silhouettes. Look to the label's collection of jumpsuits for a chic alternative to a dress. These structured styles feature fitted bodices and flared legs for a dramatic, feminine look.
