Hot Or Not: Katy Perry's Purr-Ple Frock

We suppose when you're launching a fragrance called Purr, there's really only one colour you can wear to promote it, right?

At least, that was what Katy Perry must have been thinking as she launched her debut scent, Purr by Katy Perry, in Mexico City.

The singer showed off her shapely legs in a micro-mini asymmetrical lavender dress. She also got pulses racing later in the day when she changed into another purple frock, this time an embellished dark purple number which had the singer's famed cleavage on display.

We think this is a step in the right direction... still sexy, and she didn't even need to wear latex.
