Looks like the Smurfs 2 LA premiere did wonders for celebrity style - not only did Britney Spears step out looking fab in Herve Leger, but Katy Perry also turned heads in a stunning royal-blue floral-embellished dress.
The singer wowed in her leather-skirted frock by Tadashi Shoji, which she teamed with satin Pedro Garcia bow-accented heels.
Brunette curls and marching blue earrings finished a look that we think is pure class.
