Your handbag line has gained a lot of acclaim in Japan. Do you get to travel there often?
It's been an amazing five years. I've visited several times, but the most recent was about a year ago. [The company] actually likes to shoot me in New York. Sex and the City has really taken off over there, and they love all the different backdrops. Plus, I live just a block from the factory where all of the products are made.
Why did you get involved with Samantah Thavasa?
It's been an amazing five years. I've always wanted to design - my mother was an interior designer. Plus, I've always been a girly-girl. When I was growing up, I never wanted to play with baby dolls - I always loved Barbie. I was offered the opportunity to do this line and jumped on it. I've had the chance to do my own clothing line, Riccime, but it's only available in Japan.
The bags are great - tell us a bit about the most recent line.
I was really inspired by the 80s, so a lot of the pieces have great studs and detailing.
We loved the bag Mortimer was sporting during our talk - an oversized platinum clutch from her own collection. The "Deborah" retails for just $225.
