She spent the day repping her Honest Company products for Amazon Prime Day. Jessica Alba stepped out in New York City on Monday in a striking white dress covered in large polka dots.

Following her TV appearance, the 38-year-old actress went out shopping in the big city with her friends Lizzy Mathis and Daniel Martin.

The white gown featured a sheer skirt dotted with massive black polka dots and multiple layers of frills. The 5ft7in Sin City star added a pair of black open-toe sandals with criss-crossing black laces.

She kept her accessories fairly minimal with a small black handbag with a gold clasp and a pair of large dark sunglasses. Jessica headed to a studio in New York to film a spot for Amazon's Prime Day.

'Lizzy @lizzymathis and I spent the afternoon chatting all our must haves- for travel, w Special Guest @danielmartin beauty @honestbeauty and baby!' she wrote on an Instagram post from the set.
