As soon as PVC enters the equation, you know Katy Perry can't be far behind. In fact, new rumours suggest that she and fiancé Russell Brand both plan to wear latex on their wedding day and that they've enlisted Lady Gaga's designer Atsuko Kudo to create the £3,000-a-pop costumes for the big event.

The singer's latest look as she performed her single "California Gurls" on Canadian show Live @ Much featured a pink latex dress with chocolate chip cookie print (Perry seems to have an enviable repertoire of sugar-inspired clothing choices, like this crop top with detachable lollipops).
She also wore a pair of very of-the-moment candy striper-red Chanel wedge sneaker boots (sporty pieces are huge for summer) but also had an unusual accessory: a large surgical bandage going up to her knee, because of an injury she sustained while performing over the weekend. Before her performance she Tweeted: "17 stitches later... Don't make fun of my dance moves tomorrow. That's what got me here in the 1st place! Thanks for the souvenir Canada."
