Lindsay Lohan dresses up nicely!

Just one week after appearing in an L.A. courtroom for her probation violation hearing, Lilo glammed it up for amfAR's New York Gala ... kicking off 2013 Fashion Week at Cipriani.

The 26-year-old wild child rocked a shimmery Theia gown paired with metallic Prada platform heels. Yikes ... those are some seriously high platforms!

Party on, Lilo!
