And in April this year, she wore a trio (yes, three!) blue outfits in ONE day. In a bid to promote the upcoming animated flick in Cancun, Mexico, Katy first wore a vintage-like blue and white striped tea dress, teamed with a floral print headscarf and a giant earring before switching into a royal blue lace skater dress, clenched in at the waist with a black belt, cat-eye shades and a matching blue floral headband. Wanting to continue with her Smurf-themed outfits for the evening, Katy donned a metallic prom dress and posed alongside a blue mushroom.

K-Pez is clearly sticking to her tradition of injecting a bit of character – i.e.: a blonde, female cartoon – into her wardrobe, but is she taking literal dressing to the extreme?
Rewind to 2011 and you'll remember the singer has already hit the headlines for her Smurf-y fashion choices. At the first premiere of the first film, she wore a dress featuring a super short hemline and a sequined design of Smurfette, accessorised with an impressive cartoon-inspired wild nail design.
So how will she up the ante for the next premiere? She's already dyed her hair a bright cobalt hue in tribute – will it be a blue skin dye next? Probs not considering she's now a US Vogue cover girl and with the eyes of the fashpack (read Anna Wintour) watching more than ever, her Smurftastic style is certainly more sophisticated. Stay tuned for more Smurf Perry coming soon.
