Anne Hathaway has plenty to smile about.

The busy actress was glowing on Monday in New York City while wearing a chic dress that she found at a bargain price, and it is a lifestyle choice that she believes will help the planet.

‘This is a $15 flea market dress,’ the Oscar winner revealed to Robin Roberts during her appearance on Good Morning America. ‘I’m trying to be more sustainable with my fashion choices, so I’m trying to wear vintage wherever

I can.’
