Celebrating The Retro Stripe with a style fit for a party.The Retro Stripe started as a simple take on a vintage sport sock. We knew we could perfect it from there. The sock’s evolution brought more colors, iterations and intentionality behind the style, building on itself like a gradient. The Retro Birthday Stripe is a variation and toast to the triple-striped sock that will always be the pair to reach for first.Knit from natural, unbleached cotton in a medium weight and universal fit with a comfortable, cushioned footbed.
