If we didn't know any better, we'd say Blake swiped this straight from Serena's wardrobe.
Strapless Black Maxi
Only Blake Lively can make a simple black dress look this good - TWICE
Dusty Pink Gown
It's no surprise Blake knows how to turn up the Met Gala, considering she sat on the steps for lunch every day during high school...
Blue Waterfall Dress
Spotted: A baby faced Blake sporting the same shade of blue as her on-screen counterpart.
Vest and Shirt Combo
We're still getting over the fact that THIS was Constance's school uniform - it seems Blake Lively is too because she's seriously committing to the shirt and vest combo.
Detailed-neck Maroon Gown
Blake is channelling some Upper East Side realness here.
White Blazer and Jeans
Looking like they just stepped out of a Ralph Lauren catalogue, Blake and Serena both do white blazers right.
Mesh Applique V-Necks
While we're loving Blake's mesh star unitard all on its own, we can't help but draw some similarities...
While Blake goes a little more boho, Serena Van Der Woodsen is classic Upper East Side.
Sheer-overlay Maxi Dress
While we aren't sure whose dress we love more here, we do know they both pull it off.
Looks like B has been raiding S's closet again.
Yellow V-Neck Maxi
This yellow maxi is everything - the colour screams Blake AND Serena.
While not many people can pull off a gold dress AND permed hair, Blake makes it look easy.
