The actresses took two very different approaches to style, with the blonde in a lace dusty rose gown that looked incredibly delicate and the redhead in a plunging floral print number with definite sex appeal.

Loving that side boob, Bryce!

Sienna’s wispy bangs and light makeup made her look like a princess out of a fairy tale, while Bryce gave off more femme fatale-ish vibes in her revealing gown and flowing locks.

Who’s your fave???
