Katherine Heigl first wore this electric blue Reem Acra Resort 2010 dress to the “Late Show With David Letterman” back in July of last year.

This is such a great dress for Katherine from the colour to the cut.

I love how the wrap over style of this dress nips her in at the waist.

My only complaint would be the black shoes – I think she should have gone for something bolder.

Carla Gugino then wore this dress in black to the Hollywood Forgien Press Association’s Annual Installation Lunch in LA back in August 2009.

Carla has chosen to wear the v-neck of this dress slightly higher but I think she could have gotten away with a lower cut like Katherine.

I think that Carla manages to make this dress look a bit mumsy somehow.

The T bar shoes are cute though.

Katherine wins this round for me – she looks radiant in this colour.

What do you think?
