The first pair of sunglasses which Selena Gomez wears in her new music video for “Hit The Lights” are a playful blue floral print with a slight cat eye shape. Hers look most like the UO Floral Cat Eye Sunglasses from Urban Outfitters (possibly the exact ones?). They are sold out at Urban Outfitters but can be purchased on eBay for $14.99. You can also pick up a similar pair by Full Tilt at Tilly’s for $9.99 with a black floral print.
Later in the video, she dances in a pair of two-tone pink and yellow plastic wayfarers. I haven’t been able to find this same color combo, but you can find many similar pairs for under $10.
