Ashley Olsen: Back in the Big Apple

Ashley Olsen walks behind her bodyguard while arriving at a building on Monday (April 25) in New York City.

The 24-year-old fashion designer is back in Manhattan after a quick trip to Paris with twin sister Mary-Kate.

Last week, Ashley and MK hit the red carpet together at the premiere of The Union during the 2011 Tribeca Film Festival.

In addition to their new fashion website StyleMint.com, the designing duo are also working on a line of optical frames, debuting this June!
