Unlike most pop stars, Selena Gomez has staying power, for her sense of style (or choice of stylist!) at the very least. Stepping out in London wearing this black Driver dress from A.L.C.’s Holiday 2015 collection, she was pure class and sophistication – but not in a dated way. We saw the slit skirt style going up and down the runways at NYFW, and the cutout in the back is equally on-trend.
