Blake Lively may play an uptown princess on Gossip Girl, but at the after party for boyfriend Penn Badgley's recent release The Stepfather, her leather pants and oversized tweed blazer are downtown chic.

Read How to Dress Like a Gossip Girl

1. Jacket
Blake pulls on a $550 boyfriend blazer from Smythe and pulls off the perennially stylish "borrowed from the boys" look. You can wear it too without having to borrow money. This similar style from Ann Taylor Loft is only $19.88.

2. T-shirt
The actress keeps her edgy ensemble casual by tossing on a simple white t-shirt from LnA for $59. You can splurge a little on this super-soft option, or go with this wallet-friendly tee we found at Charlotte Russe for $6.

3. Bracelet
This signature Collier de Chien from luxury leather house Hermes is beautiful, but at $1,000, it's a bit out of our price range! Steal Blake's studded rocker style for $48 with this crave-worthy cuff from Cara Couture.

4. Clutch
An outsized metallic bag holds its own next to this fashion-forward outfit. We found a cute copy cat clutch from French Connection for only $78!

5. Pants
The Sisterhood of the Traveling Pants star knows a thing or two about leg wear, including how to wear leather jeans. Take a tip from Blake and look for a style with more substance than flimsy leggings and then pair with a long blazer and edgy accessories to balance out the look. Blake opts for Helmut Lang's $875 skinny leather pants, but by going faux you can copy her style for hundreds less. The price tag on this leatherette pair from Guess is $89! 

6. Shoes
This Gossip Girl keeps her style rocking from her head right down to her feet. These studded pumps from Giuseppe Zanotti are $650, but this more affordable pair from Wet Seal for only $12.99 will make you look just as ready for the red carpet.
