One designer known for dressing ladies up for night, while the other designer does men and women's for day. NY1's Stephanie Simon has more on Tadashi and Richard Chai.

You never have to play red carpet russian roulette when wearing Tadashi. Everything Tadashi Shoji makes is monumental and meant to steal the spotlight.

"Everybody coming, 'Oh, you look so beautiful,' and that is what women enjoy," Tadashi says. "If you are not confident, you can't wear my dresses."

For Fall 2013, Tadashi was inspired the rise and fall of the Russian Empire, including the indulgence of the Russian royal family and exile in Siberia.

From Tadashi's Russian winter, we head to Richard Chai's androgynous appeal.

It's always fun to borrow from the boys, and at Richard Chai, it is especially easy with his fall looks for men and women on the runway.

Front row celebs say his ability to tailor menswear makes him an even better women's wear designer. Maggie Grace was definitely "taken" with it.

"It's very cinched in and classic, the jackets," Grace says. "So yeah, tailoring is very important in a piece like this."

Ashlee Simpson agrees.

"I love his clothes for men and women," she says. "I love that he can do both."

It makes sense to Chai. After all, he started out in menswear, and was later inspired to do women's wear by something unexpected.

"I started seeing these stylish women in New York wearing the man's top or sweater and the pants oversized, and I was like, 'Wow are they wearing their boyfriend's clothes or their own? Are they buying it?'" he says. "And that's how the idea came about. I think they go hand in hand with each other."

Chai says that sometimes, his designs for women also inspire his menswear. His vision for fall is dressing up for day, but day or night. Just make sure you grab you coat on your way out.
