See Katy Perry, Florence Welch + Jessie Ware at Prada Gatsby Party [Pics]

Katy Perry may not be on the soundtrack to the upcoming blockbuster 'The Great Gatsby,' but the pop diva and fashionista showed up at the Miuccia Prada for Gatsby cocktail party in NYC last night (April 30).

Perry mingled and fraternized with fellow pop singers Florence Welch (who is on the film's soundtrack) and Jessie Ware (who is not... on the soundtrack, that is).

See the lovely ladies of pop music hobknobbing with the fashion elite. Perry was snapped with redhead actress Isla Fisher and DJ Mia Moretti, while Flo got in tight with the film's female lead Carey Mulligan!

Perry wore a maroon flowered Prada dress and no, that's not a black leather front pocket doubling as a fanny pack type thing. It's her rectangular clutch which she's holding in an awkward fashion.

She's rocking long, glossy waves in her hair lately, and it's refreshing that she's choosing a color found in nature.

Here's Perry and Fisher looking lovely.

Perry and Moretti are a colorful and fashion forward pair.

Flo and her flame-hued locks rocked a simple black pantsuit. It's rare for her to wear something so tame and subdued.

The singer took time to pose with Mulligan, who plays Daisy in the film. They are both Brits.

Ware, a fellow Brit like Welch and Mulligan, was prim and proper in a peach jacket and a denim pencil skirt.
