FAQs

Are flat top sunglasses in style?

Yes, flat‑top sunglasses are currently trending in 2026. Fashion editors highlight the bold, angular “flat‑top” browline as part of the modern retro revival in eyewear. Tip: Choose flat‑top frames with strong UV protection and balanced proportions to make the style work.

What are flat top sunglasses?

Flat‑top sunglasses have a straight, horizontal browline across the top of the frame, creating a bold, angular look. They are fashion-forward and statement-making, often used to add an edgy or modern touch to outfits. Tip: Pair them with UV400 & polarised lenses for eye protection and choose a frame size that complements your face shape.

Do flat top sunglasses fit oval faces?

Yes, flat‑top sunglasses fit oval faces well. The straight, angular browline adds definition and balances the naturally soft curves of an oval face, creating a bold, stylish look. Tip: Ensure the frame width matches your face and lenses cover your eyes fully for the best fit.
