Queen B Gets Crowned In Marchesa, Serena Ditches Jail To Clap For Her

Last night's episode of Gossip Girl awkwardly juxtaposed the present with flashbacks of Lily Van Der Woodsen's rebellious past. Needless to say, the glimpses of Serena's mom circa 1983 featured ample shoulder pads, perms, and even some Flashdance-inspired shredded t-shirts. Thankfully, present-day Blair and Serena attended their senior prom in gorgeous couture that almost made up for a decade's worth of faux pas. 

Blair was crowned prom queen in a breathtaking Marchesa ball gown.
Topped off with a tiara, Blair, in her black silk tulle with gold leaf
appliques, looked like the UES princess we all know she is. 

Try BCBG's striped organza dress ($318) for a similarly full-skirted silhouette that's slightly more cocktail appropriate (and certainly more affordable).

Serena showed up from jail in a dusty pink Christian Dior halter gown that sparkled, literally. This maxi dress from Martin + Osa ($99.50) mimics the neckline and offers a more season-appropriate burst of color.
