Today, Lady Gaga — a woman known for her inspired headwear, charming accessories, airport style, and uncanny resemblance to Donatella Versace — turns 28 years old. To celebrate, Gaga plans to transform The Out NYC resort in Times Square into “The G.U.Y. Hotel,” a free exhibition open to the public that will commemorate her latest music video. In the meantime, she’ll be hanging out in New York, wearing creepers, purple sunglasses, and a knee-length white wig. Click though the slideshow for a look back at her style evolution through the years — from the hair bow to the flame bra, all the way back to the quaint time when pop stars still made an effort to cover up their nipples.
