Demi Lovato attended the KIIS-FM Pre-Gammy Party last week. She wore a black blazer, her Vintage Harley Davidson Righteous Ruler Biker Tank Top (sold out), a pair of Ripped Jeans similar to these from Boohoo ($55.00), a pair of Sam Edelman Darwin Boots ($159.95), a plaid headscarf and an Organic Peroxide Surf Rat Necklace ($95.00). You can get similar tees on Etsy.
