Georgina Chapman and Alyssa Milano spoke to Enstars about their own start in the fashion industry and what lies ahead in season 3 of Project Runway: All-Stars, premiering Thursday, Oct. 24, on Lifetime.

Chapman returns to judge the design competition with Issac Mizrahi and is joined by newcomer Milano, who double's as the show's host. Marie Claire's Senior Fashion Editor, Zanna Roberts Rassi, takes on the role as a mentor for the 11 former top ranking Project Runway contestants returning to compete for a prize package worth almost $1 million.

Chapman, co-founder of fashion house Marchesa, knows what the show's designers feel like when putting their pieces out for the world to judge. Though her label with Karen Craig was launched in 2004, making her practically a veteran in the industry, the former model said she still gets butterflies in her stomach when premiering a collection.

The British designer was nervous in her late 20s when Marchesa started and gets the same feeling nowadays.

"Absolutely. I'm still nervous every show. I'm really nervous," she admitted.

Chapman's fashion icons include the late English magazine editor Isabella Blow, who was also the muse of hat designer Phillip Treacy.
