Barneys New York threw a party at its Beverly Hills outpost to honor cult British handbag designer Anya Hindmarch, whose bags are all the rage in the fashion world right now [1]. Anya was in Los Angeles to celebrate the launch of her brand-new Service Station Collection as well as her Fall 2015 accessories range.

As would be expected at any big LA fashion party, a handful of starlets made the rounds including Kiernan Shipka and Jena Malone — but the most curious guest of all, perhaps, was a Hood by Air-clad Justin Bieber. Is it possible that Justin, like the rest of us, can't get enough of Anya's fun and colorful designs?

Possibly, but it turns out Justin has a personal connection to Anya's creations. He was there to honor his friend and stylist Karla Welch, who cohosted the bash with Jena. "Long day," Justin wrote on Instagram [2]. "But had to come and show love to my girl Karla!" The affection flowed both ways, evidently, as Karla made sure Justin left with a personalized jacket.

Read on to see snaps of the celebrities at the event and highlights from Anya's eye-catching new collection.
