Retro Flat Metal Dapper P-3 Horned Rim Sunglasses
First step, take the popular P-3 style that everyone loves and make a mold out of it. Next, cast the mold with molten iron and let it sit. Finally, take out the cast and flatten it to get that cross-era feel. Now of course it's not that extreme, but here's the new P-3 style. Made with metal frame, metal hinges, and UV400 lenses.
