On Monday night in the US ‘Gossip Girl’ aired episode 8 of Season 4 titled, “Juliet Doesn’t Live Here Anymore.”

I won’t give the storyline away because I haven’t seen it myself as it airs tonight in the UK, but it looks like the girls are going to a grand ball as they’re all looking very elegant in their gowns.

We’ve already seen pictures of Leighton Meester in Ralph Lauren with a Judith Leiber clutch and Christian Louboutin heels, plus Blake Lively in Zuhair Murad with a Halston clutch.

The additional pictures are of Katie Cassidy and Jessica Szohr.

Katie wears a stunning blue pleated J. Mendel Spring 2010 gown with nude cap sleeves.

Her look is paired with a stunning Ranjana Khan necklace and Carlos Falchi clutch.

We’ve seen this gown worn by Tatiana Blatnik and Vera Farmiga.

Jessica wore a printed Christian Cota Spring 2010 gown with a ruffled neckline. Her gown was paired with a tan Lauren Merkin clutch.

On the runway the J.Mendel is my favourite look, but I’m not crazy about how it looks on Katie as it has too much added to it for such an ethereal gown.

On the ‘real-way’ I just love the Ralph Lauren gown on Leighton. It’s the perfect chic look for the Upper East Side princess.
