Who knew Taylor Swift's jumpsuit at the Billboard Music Awards would cause so much "trouble, trouble, trouble" ... ?
Fashion brand Nasty Gal implied that Swift wore their $78 dress to the award show -- but as it turns out, she was actually wearing the real Balmain jumpsuit, which is worth $5,000.
Nasty Gal took to Instagram, writing, "One piece wonder. @taylorswift in the #NastyGal Frisco Inferno Jumpsuit at the #officialbbmas. #NastyGalsDoItBetter."
The Balmain designer himself then basically confirmed the mix-up on Instagram, captioning a photo of Swift and pal Lily Aldridge with "Balmain Girls!" The original dress worn by a model walking the runway last September is reported to cost around $5,000 based on similar styles, but it's not for sale.
Since Nasty Gal quickly deleted their post, it's safe to assume that it was an error on their part and someone at the office mistook the expensive dress for their $78 knockoff.
