Among those who opted for the least subtle outfits were Cardi B (who still has people talking about her appearance on the Billboard Music Awards red carpet from last week), Lady Gaga and Katy Perry.
The gala may have been decorated with a pink carpet, but Cardi brought her own red carpet, and it pretty much took up the entire staircase.
Gaga, meanwhile, kept onlookers guessing by donning not one but four different entrance looks. Beneath a massive poof of pink satin there was a black evening gown, another pink evening gown, and a bedazzled lingerie look.
Perry was another unforgettable star that lit up the pink carpet, showing up in full chandelier garb. After the entrance, though, she also opted for a wardrobe change — slipping into a slightly more comfortable giant rhinestoned hamburger costume.

Plenty of other stars also serve major looks, including Jared Leto, who showed up with his own head in his hands; Shawn Mendes, who caught Leto's head when it was thrown at him; Janelle Monáe, who showed off her eye for style; and Lena Dunham, who showed up dressed as a rubber fetishist couple with Jemima Kirke.
