Kaley Cuoco, Jim Parsons & the Rest of the ‘Big Bang Theory’ Cast Got All Gussied Up for Their Series Finale Party

It’s the end of an era for the Big Bang Theory cast. So last night they celebrated like it was 1999 season one.

The cast toasted the upcoming bittersweet end of the hit CBS series, which takes its bow on May 16, with a little party. Now this wasn’t any ol’ wrap party. There was a red carpet involved. So, Kaley Cuoco, Jim Parsons and the rest of the cast rose to the occasion and dressed the part. Here, five Big Bang Theory cast members looking nothing like their characters.

Kaley Cuoco

The IRL Penny looked all glammed up in a sultry Carolina Herrera black pantsuit with cutouts at the waist, an Edie Parker handbag and Anita Ko jewelry.

Kunal Nayyar

Nayyar may play a geeky Caltech astrophysicist on the series, but in real life he’s super suave and looks pretty darn comfortable in that velvet Gucci blazer.

Melissa Rauch

Don’t be fooled by Rauch’s sequined DSquared2 frock, she’s still Bernadette from the block…at least until May 16.

Jim Parsons

Pink blazer, pink tie and a printed pocket square? Sheldon might not appreciate the pop of color, but we totally do.

Mayim Bialek

Like her fellow female co-stars, Bialek opted for a chic black ensemble and dressed up her LBD with some wire-frame glasses and a lot of wrist bling.

Johnny Galecki

Leonard may not be a statement blazer kind of guy, but Galecki totally is. I mean, that leopard print lapel? Rawr.

And that, friends, is how to go out with a bang.
