Jessica Simpson on the “Fashion Mentors” on the new NBC show Fashion Star. Aspiring designers will compete for buyers like H&M and Macy’s to actually put their designs on the market the day after the show airs.

“I definitely look at comfort,” Simpson said. “I buy bigger sizes which is very important but I haven’t really gone to maternity clothes. I don’t really love a lot of maternity stuff so I’m using it as a fun business thing to do. The next thing you’ll see form the Jessica Simpson Collection is maternity.”

As a mentor, Simpson shared some of her advice for new designers just breaking into the business. “I personally think that it’s important to understand who your consumer is and once you get detached from that, thinking you’re this hotshot designer is when everything goes to waste. It’s really being able to be a relatable person and brand and being able to translate that into your garment.”
