Leighton Meester stole our hearts when she took to the red carpet to attend the 14th Annual Hollywood Awards Gala in this stunning Elie Saab tulle ruffle dress powder blue dress back in October, which is from the Spring 2011 collection.

The actress looked incredible in her tulle cocktail dress which features subtle sequin detailing and a thin satin ribbon tied into a delicate bow around the waist. She was the first celebrity to wear a look from this beautiful collection.

Leighton played up the sweetness of the dress by pairing it with matching baby blue suede heels from the same collection plus a glitter-embellished Jimmy Choo ‘Candy’ clutch.

She wore her hair in a pretty up-do with a few strands of loose curls left out and kept her makeup soft, wearing a coral shade of lipstick.

Astrid Munoz wore the same dress to attend the ELLE Awards 25th Anniversary in Madrid, Spain last night.

The Puerto-Rican model took a decidedly different approach, wearing her hair in a centre-part bun and pairing the dress with electric blue Charlotte Olympia ‘Paloma’ platform pumps and an oversized cocktail ring and statement earrings.

It’s hard to top Leighton in this dress considering how lovely she looks, but she wins for me because I think Astrid’s hairstyle is too severe for such a sweet dress and definitely think her shoes were the too stark in contrast to her soft delicate dress.

Leighton worked this pretty, lady-like look perfectly and therefore wins by a long mile.
