Super cute

Very cute! I like the shape and they fit my face nicely, just big enough without looking crazy.

I’m absolutely loving these new glasses.

They are the perfect compliment to any outfit. The shape is perfect for my face and the spring hinges are a must. They are lightweight and comfortable to wear all day. Going to purchase them in another color since I love them so much!
