So simple and clever. I’m really into the design. To recreate, polish a diagonal stripe with black polish and use a dotting tool to place the polka dots. Pouring out the polish onto a piece of aluminum foil will help it thicken a bit, which makes applying the dots easier. Just work fast or the polish will get too thick.
