Mary Kate Olsen New York stripes jeans sandals

Mary-Kate Olsen handled her new $4000 shoulder bag from her fashion line (with sis Ashley), The Row on Friday. Interestingly enough, the fashion maven paired the pricey bag with a classic striped French sailor shirt, jeans, Birkenstock sandals and wet hair!

The ladies' new line of purses range from about $2500 to a $39,000 ostrich leather backpack. MK may carry her red bag to the market but we doubt we'll see many NYU students in her 'hood porting a $40K backpack to class!
