Affordable Upgrade from Cheap Sunglasses
These sunglasses are stylish, comfortable, and well-made. They came with a really nice case and a soft bag that doubles as a cleaning cloth, which is super handy. I love the shape and style of the frames — they’re flattering without being over the top. The lens color is dark enough to block the sun but not so dark that it makes everything hard to see. The overall quality feels solid, especially compared to the cheaper sunglasses

Cute and was exactly as expected
It is exactly as shown. I have a very small head and these did not slip down my nose. The lens is large as it says in the description but I like the coverage from the sun. Great price!
