Is Alexander Wang getting his inspiration from rival designer Prabal Gurung, or are they just swapping similar ideas? Fashion-world insiders raised a carefully groomed eyebrow when Wang released a promotional music video with hot hip-hop artist Santigold Wednesday to show off his resort collection two weeks after Gurung used the same format with hip-hop artist Rye Rye to show off his own collection. Both female rappers dance wildly in a flashy, pop-art style with similarly styled blond hair while showing off the resort lines behind the flashing names of the brands. “Alex Wang must have been pissed when he realized Prabal beat him to the punch in getting the video out,” a fashion insider speculated. “It looks like he just copied directly from Prabal.” Wang’s rep said “no comment.” Gurung’s rep didn’t get back to us.
