Lady Gaga has proved time and time again over the years that she’s more than willing to go the extra mile in the name of her craft, so it should come as no surprise that she once spent three days inside of a plastic egg just to make sure she stayed in the right headspace.

The pop star took a look back at some of her most iconic outfits in a new video for British Vogue, pausing when she came across her unforgettable, enigmatic entrance to the 2011 Grammys. “We would call this an outfit,” she said while looking at the photo. “Everyone calls this the egg but it’s actually a vessel that was designed by Hussein Chalayan.” She went on to explain, “I was very particular about the way the fashion looked for this performance in so much as the night before the performance I said, ‘The fashion’s wrong, we don’t have it. We need it to be latex. We need nude latex.’” Both Gaga and the crew that carried her down the red carpet in the egg were dressed entirely in swaths of tawny latex.

But Gaga pointed out that this last-minute wardrobe change was no easy feat to pull of, especially a decade ago. She said, “If you know anything about looking for latex, years ago it was very difficult to find latex anywhere other than a sex shop, or—where we found this latex was a bus company had latex that they were using to cover the seats of their busses and we found the latex and we asked if we could buy it from them. So everybody’s fashion that’s made here was made from the fabric from seats for a bus.”

But it wasn’t enough just to have the right look, the musician also needed to be in exactly the right state of mind for the big night which meant going to some pretty extreme lengths. “I was in the egg for three days,” she told the magazine. “To be honest, at award shows, especially during this time, I didn’t like to talk to people. I always felt that it threw me off with my performance so this in a lot of ways is really representative of my devotion to my craft in that I really wanted to be with myself.”
