katyperry90sstyle.jpgEver loveable Katy Perry joined a host of celebrities at a roller rink this weekend to celebrate her stylist's birthday - and it certainly looks like she had a blast!

As her divorce from Russell Brand finalised yesterday, it's nice to see that the Fireworks singer took a little time off from promoting her documentary film, Part Of Me, and spent some quality time with her friends. The bubblegum beauty partied at the Moonlight Rollerway in LA with birthday boy and new America's Next Top Model mentor, Johnny Wujeck, for a night of Nineties themed fun. Wujeck, who is replacing Jay Manuel on ANTM, encouraged his 'Juan Sweet Roller Skate Party' guests to dress accordingly, issuing a 90's dress code via twitter and stating that there would be a trophy for the best dressed. We wonder who won?

Katy skated alongside friend and designer Jeremy Scott, as well as Hollywood celebs such as Lindsay Lohan, Rachel Bilson, Amber Heard and Zoe Saldana. Although her sunglasses were more 50's than 90's, the 27-year-old took the theme seriously; did you expect anything less from the dressing up queen?! Katy opted for a colourful ensemble consisting of a matching floral cropped vest and cycling shorts, washed denim shorts, hoop earrings, stacks of plastic bracelets, a tattoo choker, hair scrunchies, and a purple rucksack filled with Beanie Babies!

Although parts of her attire were a little too 90's for me to handle (if the choker ever comes back, I think I'll cry) the majority of the look was bang on trend. The decade that brought us cropped tops, creepers and tie-dye is still influencing the way we dress at the moment, and looks as though it will continue to do so for the rest of the year.
