Mary-Kate and Ashley Olsen claim Michelle Tanner wore Chanel

(UPI) -- Noted "duck-face" enthusiasts, designers and actresses Mary-Kate and Ashley Olsen granted a rare interview to Net-A-Porter's The Edit, in which they discuss their high-end line The Row and the origins of their interest in fashion.

For the 27-year-old twins, their interest in "fit" and style started with their extensive wardrobes on the set of "Full House," in which Mary-Kate and Ashley took turns playing Michelle Tanner.

"We’d be in six-hour fittings three times a week, because we had to wear 12 different outfits,” Ashley said.

Some of those outfits included pieces from designers like Chanel and Marc Jacobs.

“We were designing clothes for ourselves as we were so petite,” Mary-Kate added. “So I think that is when we became obsessed with fit, and now the obsession has become a profession.”

So when you thought little Michelle was wearing overalls made by Kmart or OshKosh B'gosh, you were wrong.

The Olsens added that their interest in staying out of the spotlight is reflected in their line, which aims for simple but well-made clothes that wealthy people can mix in with their even more luxurious goods.

“We saw a space in the market,” Ashley explained. “We knew there wasn’t another brand offering basics in a luxurious and contemporary way."

"If I wear certain designer brands, or too much of something, I look crazy, and I need something to break it up," she added. "If you are wearing a Chanel jacket and you need an anonymous piece that will show just how special that jacket is, I hope that is what The Row gives you.”
