On Monday night's Gossip Girl, Olivia (Hilary Duff) decided to show Dan's parents that she really is the shallow Hollywood starlet she believes they think her to be (yeah, lots of lies this ep), so she rolls up to the Freshmen Parents Dinner/Toast/Impossible Social Situation in a skin tight, peach Hervé Léger.

Over on Monday night's Castle, Beckett (Stana Katic) needs to remind everyone that she is a hottie in addition to a bitchin' detective, so she rolls up to Castle's book launch party in a skin tight, blue Hervé Léger.

On Gossip Girl, this sort of thing is expected. Also, TV has long conditioned me to accept that people on inside the tube wear clothes, live in houses, and drive cars far beyond their salary range, so I'm okay with Beckett's choice. But twice in one night on two different networks? What's next? Will Quinn be in tears on Glee tonight when her Herve Leger no longer fits? Will Jonathan have to solve the case of the stolen Herve Leger on Sunday's Bored to Death? Remember: twice is a coincidence; three makes a rule.
