Square

Quince's women's square sunglasses cover polarized acetate frames (in tortoise patterns and solid colors — black, brown, jewel tones) and stainless steel frames (thinner, more minimal in metal finishes). All with polarized lenses that cut glare in bright conditions. The square silhouette runs across small, medium, and oversized frame sizes depending on style.

Square sunglasses suit rounder face shapes especially well — the straight lines balance soft features and add visual structure. They also work across oval and heart-shaped faces because the moderate-angle frame doesn't compete with strong natural angles. For naturally angular faces (square, rectangular face shapes), curved styles (round, oval, aviator) often flatter more by softening the natural lines.

Acetate — the traditional sunglasses material. Lightweight, warm against skin, with depth of color and visible material thickness (especially in tortoise patterns). The classic sunglasses look. Stainless steel — modern metal frames in gold, silver, gunmetal finishes. Thinner profile, lighter weight, more minimal aesthetic. Choose acetate for warm-toned classic styling; choose stainless steel for minimal modern looks.

Clean lenses with a microfiber cloth and lens cleaner — never paper towels (which scratch coatings) or shirt fabric. Store in the protective case when not wearing to prevent scratches and frame warping. Avoid leaving sunglasses in hot cars or direct sun for extended periods — heat can warp acetate frames and damage lens coatings. With proper care, polarized lenses and acetate frames hold up across many years of wear.
