Ashley Olsen in a Maxi Skirt in NYC Pictures

Ashley Olsen left an NYC building this morning carrying a luxe handbag from her high-end collection The Row. Ashley and Mary-Kate's new StyleMint line debuts this week, and the launch of the sisters' latest fashion endeavor comes just after their 25th birthday, which was earlier this month. Their affordable shopping service comes from the same team that brought us Kate Bosworth's JewelMint, and Mary-Kate and Ashley's first offerings through the site will be a range of eight t-shirts. The Olsens have clearly been hard at work on the new effort but have also taken some time out to attend stylish events in the city lately, including the CFDA Awards and the Met Ball.
