Don’t worry, be happy. That seems to be the posture Alexander Wang is taking at Balenciaga. For spring, his second outing at the house since the departure of Nicolas Ghesquière, who took Balenciga to the bleeding edge of design, Wang let the light in — literally and figuratively. Early this morning, in the grand Observatoire de Paris, the ceiling was pulled back to allow an ocean of sunlight to drench the runway and his equally sunny collection.

The show opened with structured skirt suits in tightly woven leather, a nod to Cristóbal Balenciaga, followed by sporty running shorts and tanks, a signature of Wang’s. With the fusion of the two designers thus forged, the rest of collection played out on perfectly pretty and safe terms. Models bounded down the bright runway in a range of happy sundresses, short shorts, tennis whites, midriff-exposing tops, transparent overlays, flower prints, and lace.

There were some interesting cuts that lent sculptural intrigue — notably capelets, batwing sleeves, and zippers that created a peel effect. But by and large this was not a show to shock; it was a show to soothe.
