This was the most cohesive and accessible outing yet from JW Anderson — one of London’s brightest new stars and a hot show ticket this week. There was a strict femininity at play here: The opening look was a white, strapless bandeau top that had wide pleats falling above a bare midriff. It was teamed with a pair of gray shorts hemmed with a white ruffle. Ruffles ran throughout the collection and, in some cases, came cascading from under the arm to fall at the hip on sleeveless knits. The designer’s commitment to experimental fabrics was most successful in a white and blue trouser suit that looked to be made of Neoprene but was, in fact, screen-printed cotton sponges. His prints looked like painterly daubs of color on white backgrounds, and appeared on pajamalike trouser suits and in a full skirt.
