Mary-Kate and Ashley Olsen hung out with sister Lizzie to celebrate her Nylon Magazine cover at a private dinner at Sons of Essex hosted by A/X Armani Exchange.

Lizzie is featured on Nylon's October "It Girl" issue. As a gift, the eldest Olsen girl was given a A|XX 20th Anniversary Limited Edition Chrono Watch. Oh, the perks of being a cover girl!

Olsen tells the mag:

    "I have to attribute the way I have always looked at [work] to my father, because he was a really good influence on us.  It was always very important to him that his daughters be financially independent.  He wanted us to know that we could take care of ourselves, because he never liked the idea of us needing a man."

She adds, "Witnessing how my sisters can take care of themselves financially was a great model to have.  I consider myself lucky to have such a normal family."

Well put, Lizzie!
