But she wasn't alone in her style misstep -- this week saw flashback faux pas from some of TV's hottest characters, including our beloved Elena (Nina Dobrev), who rocked an unfortunately ill-fitting cheerleading uniform for the big "Vampire Diaries" season finale, and hot, brooding Jack Porter (Nick Wechsler), who was hiding under a stringy black Raggedy Ann wig in "Revenge" flashbacks.
Thankfully, there were some all-time best dressed looks to get us through, like a sexy duet for Ivy (Megan Hilty) and Karen (Katharine McPhee) on "Smash" that finally showed off their assets ("Real Housewives of Atlanta" star Phaedra would not hesitate to call these what they are: donkey booties), and an entire episode full of shining style moments for Megan Draper (Jessica Pare) on "Mad Men." Seriously ... can we live in her closet?

It takes effort to make Nina Dobrev look less than stunning, y'all ... and a big effort was made here. Cheerleading outfits are a fantasy for a lot of people, but somehow this is much more of a fashion nightmare.
Va-va-va-voom, ladies! We've been waiting all season to see Ivy (Megan Hilty) and Karen (Katharine McPhee) share a moment in the spotlight, and they stole the "Bombshell" title right out from under that so-called movie star in this sexy number.
What does Christina Aguilera have against wearing pants? Her season full of bizarre leather diapers (the cute, petite versions are usually called "hot pants" -- these are diapers) came to a grand finale with these leather, studded ones. Need we say more?
Megan Draper (Jessica Pare) is hands down TV's best dressed female, turning out stunning looks no matter where she's going. This houndstooth ensemble puts her two competing universes in perfect balance. And don't even get us started on that fabulously glossy green trench she wore this week, too. Divine.
Ladies and gentlemen, I give you Jack Porter. <em>Seriously</em>. This is brooding heartthrob Jack Porter, circa 2002. <em>Seriously</em>. Not 1969 or 1985 ... this hair supposedly happened at the Stowaway in 2002. It's enough to make us not want another Hamptons flashback for a while ...
Liza Lapira's immense comedic talent is somewhat wasted in this way-too-small supporting role, but for all of Robin's funny quirks, sometimes she can really pull out a cute look. No, she's no girl next door like June, or a vixen like Chloe, but this cozy, colorful sweater makes her way more relatable.
She schemes, she lies about needing a wheelchair and she's got a bad attitude (again) ... basically, we're so over Quinn, and her flip-flopping fashion choices aren't helping.
Dr. Lee (BD Wong) is killing it on one of the most intense, fascinating new dramas on TV. Look at that face, so genuinely concerned ... then notice how perfectly put together this therapist is. The only man who rivals this is Wong -- his own personal style makes this look downright dull in comparison.
