Happy Endings‘ stylish stars: Elisha, Eliza & Casey

Elisha plays the sometimes scatterbrained Alex on Happy Endings, but last night the actress was 100 percent professional and polished.

“I’m wearing an Anne-Catherine dress and Rachel Roy shoes,” Cuthbert told us.

Elisha’s fashion icon?

“Cate Blanchett,” said Cuthbert. “She is incredible. Every time I see her on the red carpet, I feel like she nails it. She just has such a great style. I wish I was 6’ 2″.”

While Eliza’s character Jane is a bit of a know-it-all, Coupe herself is way more laid-back. When we complimented her on her killer style, the actress admitted she wasn’t even sure which designers she was sporting.

“I had a malfunction with my shoes so I had to borrow from wardrobe, and they dug out these witch looking things, but I actually think they are kinda fun,” said Coupe.”

So who does she take her style tips from? “Kate Moss,” Coupe said without hesitation.

And for her beauty needs… “Sunday Riley’s skin care. The entire line. It’s the best thing that ever happened to me.”

Sneak previews of season 3 indicate that Wilson’s character Penny is headed for a full on body cast this year, but last night Casey’s white number was way more Grecian goddess than hospital gown.

The actress rocked a gold leopard Jimmy Choo clutch with matching Jimmy Choo black and gold heels.

Her favorite celeb trendsetters? “I love Diane Kruger. I think she’s so beautiful and Gwyneth Paltrow.”

Want to get Wilson’s just-been-kissed glow? “Nars Orgasm Blush,” she revealed.
