Katy Perry rocks a head-to-toe blue look while making an appearance at The Americana at Brand on Wednesday (February 22) in Glendale, Calif.

The 27-year-old pop star also drove up to the outdoor mall in a light blue convertible, where she greeted fans and promoted her line of fake eyelashes she created in association with Eylure.

“Today has been a BEAUTIFUL day! U debuted ‘Part Of Me’ at #1 & now I can’t wait to bat my LASHES & thank u in person @ the Americana at 4pm!” Katy tweeted earlier in the day.

FYI: Katy is wearing a Roland Mouret dress with Giuseppe Zanotti heels. She accessorized with a Solange Azagury-Partridge ring, vintage bangles, and her own diamond studs.
