2018 amfAR Gala: Katy Perry peacocks in powder blue, Carmen Electra nails navy and more looks of the night

Great style for an even greater cause!

The 2018 amfAR Gala, which benefits the global fight against HIV/AIDS, was a star-studded affair featuring guest of honor Katy Perry, who was presented with the night's Courage Award. And she certainly embraced the title: Perry's powder-blue feathered gown was the definition of a courageous fashion choice, but she -- as always! -- pulled it off.

On-and-off boyfriend Orlando Bloom was also in attendance, but the two reportedly stayed away from each other until they were seated together inside the event. (Thoughts on the buzz cut? Anyone else miss the dark curls of his "Pirates" days?)

Also glowing at the star-studded affair was Carmen Electra, whose form-fitting mermaid gown showed off her famous figure, and Rumer Willis, who opted for a seasonal buttery yellow.

Meanwhile, Robin Thicke and his pregnant girlfriend also posed for the paparazzi.

Inside the event, guests enjoyed glasses of Perrier-Jouët and incredible prizes were auctioned for charity: A golf outing with Andy Garcia, luxury custom-designed TOMS shoes, and trip to Disneyland with Katy Perry herself.
