Mary-Kate Olsen stepped outside NYC's St. Ambroeus restaurant yesterday to smoke with a guy friend. She brought her glass of rosé along for the chat, too. It was a fun evening out for Mary-Kate during a break from work on her assorted fashion venture. She and sister Ashley just launched their StyleMint t-shirt site, and tonight will launch their line of handbags for The Row. In an interview with Barneys, Mary-Kate and Ashley shared style tips. Ashley said her favorite pieces are, "A great pair of vintage jeans, a tailored suit, a crisp white button-down, Parisian stripes, and a great men’s watch." Mary-Kate added, "I dress for me and usually whatever suits my mood." As to which famous person's closet Mary-Kate would like to raid, she said it would be Pablo Picasso's.
