Cute glasses. Not very sturdy and the ear pieces seem loose. They are okay for the price.

So cute and feel durable. The color looks exactly like the photo and the fit is great they're not too big which is something I find often when ordering glasses online. Will definitely be purchasing a second pair.

Ding! Ding! Ding! We have a winner!
Color: Boho Multicolor, Size: XX-Large
Wow. These are really nice tops. The material is soft and very comfortable and the fit is true to size. Colors are as pictured. They look and feel like they cost a lot more! I initially order this in 2 different patterns (Boho and Willowfloral) and I just now ordered 3 more, black, purple, and wine red. Can easily be worn all year round and can be dressed up or down. All in all, I’m very pleased with this purchase.
