Perfect shades
Color: Tortoise Frame/Brown Lens
I love these sunglasses! I have a small face, and I find that these fit perfectly! They are stylish, fun and I don't have a problem of them sliding down my nose.

Quality for lower price than brand sunnies
Color: Beige Tortoise Frame / Brown Gradient Lens
High quality for a low price. I'm someone who always loses my sunglasses so I won't allow myself to purchase any name brands. I've had my fair share of cheap sunnies for this reason. These are probably the best "off-brand" I've tried - and I've tried a lot. They are definitely polarized and are lightweight with a good fit - some of the cheaper brands are really tight on the ears and the plastic is clearly cheaply made, making them heavier. They are also a cute style with a variety of colors available. The other thing with cheaper sunglasses is they are usually not that great to peer out of. Some of them I can't wear to drive bc they are too dark, or not dark enough for glares on the road. These are great for driving - the lens coloring is just right to see well and also feel like you're not squinting. I'm buying another pair for when I inevitably lose these!

Polarized sunglasses are just what I needed
Color: Tortoise Frame / Mirror Pink Lens
I really like these sunglasses. They are polarized and work great. They fit well and don't fall off when I bend over, which is important. They are light on my face and don't make marks or pressure on my nose. The color is perfect and they are really cute. They are a great value, well worth it. The cleaning cloth and bag to keep them in are a bonus. Very comfortable!
