Dianna Agron was pretty in pink on the red carpet at the “I Am Number Four” LA Premiere last night.

The “Glee” actress looked very graceful wearing Vivienne Westwood Red Label Spring 2011 dress.

I love the ruby Brian Atwood pumps she added to her draped pink look, but I wish she’d gone one step further and added a contrasting coloured clutch instead of the matchy VBH pink clutch.

The danger of this colour for Dianna is that it could’ve washed her out.

Thankfully the pumps prevent that.

I love this dress, but I prefer the length as it was presented on the runway.
