Ariana Grande celebrates the release of her debut album Yours Truly with a performance on The Today Show. She wore a white bustier very similar to this from Nasty Gal ($38.00), the Bosstones Skirt by Kenley Collins and a pair of Jeffrey Campbell Darling Pumps ($180.00). You can get the look with a skirt from ASOS by River Island ($13.50) and Missguided Pumps ($51.12).
