This week, Nylon magazine held a launch party for their October issue and the Hello Kitty Forever collection at Forever 21, and lots of Hollywood's top young stars were there.

Bella Thorne wore leather leggings, a red off-the-shoulder top, and some detailed heels. She kept her makeup and hair casual and cool.

Olivia Holt chose a pretty blue lacy dress, which she wore with a black belt and chunky black heels. She added a simple gold pendant to finish off her cute look.

Sarah Hyland went for an edgy look, pairing a white girly collared tee with a liquid-look silver skirt. She wore her hair in a high bun and had on dark lipstick.

It looks like it was a really fun party!
