Ashlee Simpson looks as though she's ready to step onto the beach with this cute white dress!

The flowy frock, paired with her floral headband and neon yellow flip flops, looks absolutely adorable on her.

Jessica's little sis, who left son Bronx at home, hit up Kitson in Beverly Hills for a late night event. No doubt, the blonde fashionista found a few things to buy along the way.

Would she hold her own bags? Nope ... that's what her assistants are for!

Lookin' good, Ash!
