While stars like Jessica Biel and Jennifer Garner were laying on the romance at last night's "Valentine's Day" premiere, Jessica Alba seized the opportunity to channel her inner peacock/flapper in a feathered Proenza Schouler dress.

While I appreciate the flirty nature of the dress (peacock has been on the rise since last spring), its lack of shape and the pairing of those navy and green corked Marc Jacobs platforms look somewhat ammature. Hey, it would make a good Halloween costume.

Have something to say about this daring style? Sound off in the comment section below.
