Katy Perry is a woman that knows just how to grind traffic to a halt. The Teenage Dream singer turned up to the Radio 1 studios yesterday sporting an impossibly tight-fitting dress teamed with impossibly high Mary Jane platforms.

Her polka dress, from rockabilly emporium Wheels & Doll Baby, gave a 50s pin-up flavour to the ensemble. Just one hitch, Katy - you do realise that your fans can't see you on the radio?
