Review on Gunmetal Transparent Ray Ban Wayfarer Sunglasses by Brooke Rogers

I bought them on November 29th. I really liked her. You are perfect in everything the seller said. the perfect sunglasses. My question is I just realized I'm the wrong size. I bought all three together and bought this particular set that I was hoping to trade in for a 52/18. I love them all, they are perfect. ? I've only worn them once or twice, they seemed big so I left them alone. Only now I realized that due to the wrong size I will never wear them, please let me know my future steps in the exchange process. Thank you!
