As Met Gala's co-chair, Katy Perry went all-out this year pushing her fashion limits to the edge.
The 19-year-old personality appeared to be breaking the strict Met Gala no-selfie rule - reportedly set in 2015 by the event's chairwoman Anna Wintour - by taking and posting the photo online. Her sister Kendall Jenner wore a sheer slip that left little to the imagination. Unashamed, she wrote: "In my rightful place, lurking behind a Jonas #MetGala".
The red carpet showcased not just some great style moments but also s0me adorable couples, and Chrissy Teigen and John Legend and Blake Lively and Ryan Reynolds were everyone's relationship goals as usual. In fact, she had to be sewn into the look before rocking the red carpet.
Much like Rihanna, Lady Gaga is notorious for stepping out in show-stopping ensembles at major events like the Met Gala. Apparently Madonna thought it was pretty amusing too...
See all the sexy, odd and most revealing looks from the Met Gala 2017 red carpet.
While the bravest fashion lovers prevailed, the majority fell short of making last night what could have been the most interesting red carpet of all time.
Kim shared the same picture on her own Instagram account and captioned it, "And what would the Met be without that squad pic?!"
At an event where plenty of her peers made risky outfit choices to stick to the evening's theme, both Kendall and Kylie Jenner opted for their usual naked-dress formalwear. Her thong bodysuit underneath was hand-painted onto her curves. "We've actually already talked about it - when we're all going to rush off".
