Isaac Mizrahi has been building foundation garments such as corsets and bras into his evening gowns his entire career. Now the designer has announced that for the first time he will be creating a lingerie collection. Isaac Mizrahi New York Intimates to launch next spring.

"Christian Dior said, 'There is no fashion without foundations.' Undergarments are so wonderful and interesting to me, and now it's all about shaping and enhancement," Mizrahi said. "That really excites me because you can be all of these things -- curvy, busty...The idea is to build a collection of intimate apparel around shapewear."

He thinks the bra is the most import piece of lingerie a woman puts on (I'd agree).

"There's hygiene and health issues with a bra. I take the engineering of a bra very seriously...I had a style show on TV and there are so many things, things that change all the time with bras, especially as you age and how the breasts change...it makes you grumpy if your undergarments aren't right and if a bra doesn't fit right."

Lingerie isn't the only thing coming down the pike. Swimwear, men's shirts and ties and more of an international presence all seem to be in the works for the brand.
