These Polaroid sunglasses for women are true stars thanks to an unforgettable design that nods to retro aesthetics. The square shape is alluring, and the slender acetate structure has been pared down for modern relevance. On both the monochromatic and two-tone versions, a metal rivet brings the shimmer of light to the front. The frames can be fitted with prescription sun lenses, confirming their practical, must-have character.
