Katy and Taylor's White Party Dresses

Katy Perry, Taylor Swift and Russell Brand pictured leaving Katy's White themed birthday party.

Katy was in a lovely white Herve Leger bandage dress, which ended the night brightly hand painted.

And Taylor was in a sweet Amy Claire frock (also party customised with color). She accessorized with a glitzy Lauren Merkin "Eve" clutch and wore metallic Fendi heels.

The Lauren Merkin "Eve" clutch, also used by Hayden Panettiere is available on-line at shopbop.com.
