The beautiful Blake Lively of Gossip Girl fame looks simply heavenly in a yellow gown at the Seventh on Sale dinner gala in New York City Thursday.

Seventh on Sale is the world's largest sample sale, in which dozens of big-name fashion brands have donated thousands of items to be sold through December 7, and 100 percent of the money raised in the process goes to services and housing for those living with HIV and AIDS. It's nice to see Blake Lively support a good cause.

And looking wonderful. See below.

Blake Lively and her Gossip Girl mates are on hiatus this week due to the holiday, but return with an all-new episode Wednesday, November 28.
