Sofia Vergara always undergoes at least three outfit changes each day.

The Modern Family actress is one of the most stylish women in Hollywood, and always hits the red carpet in designer ensembles from the likes of Versace, Michael Kors and Zuhair Murad.

But Sofia prefers less glamorous outfits when she's off-duty, which means she has to switch-up her looks several times over the course of a day.

"My husband (Joe Manganiello) always makes fun of me because he says that I have like, three outfits a day," she told coveteur.com. "He says that I have my outfit that I go out in, then I have my loungewear - because as soon as I get home, I don't want to be in tight jeans or a dress - I always have an in-between thing, because if it's 4pm, I don't want to put my pajamas on. If I'm going to be at home, I don't want to be uncomfortable."

Sofia justifies all of her outfit changes because she thinks it is important to be comfortable but "cute at the same time". The 45-year-old injects the same ethos into her new EBY subscription-based underwear line, which she has developed with business partner Renata Black.

"So, Renata sent me the underwear, and I'm like, 'I can't live without this underwear!' It's amazing, it was super practical," said the brunette beauty. "It doesn't roll, it's not uncomfortable, it's seamless, nobody can tell that you're wearing underwear, and there's also a style that holds you in more."

Ten per cent of net sales of EBY products will go to the Seven Bar Foundation, which looks to microfinance and benefit underprivileged women around the world. And Sofia is pleased that women will not only be able to feel good about buying the products, but look good too.

"We wanted to have fun with the prints and the basic colors - which is what we usually wear. No matter how sexy we are, we use the basics, which is the nude, the black, the white, the grey. And then prints for fun," she added.
