Over the weekend, Emma dressed up as her aunt Julia Roberts‘ character in Pretty Woman for a Halloween party.

Emma recently compared her app Snapette to other social media apps.

“You can upload photos like on Instagram, but then it’s also like Yelp in a way – that you can find what stores are nearest to you, which is awesome,” Emma shared with WWD. “It’s great, because I’m always the kind of person that’s like, ‘Where did you get that?’”
