Very sexy sunglasses!
Style: Chic Metal Rectangular Shield, Color: Rose Gold & Rose
I loooove these! I would rate 5 star, but the lens developed a small crack by the earpiece, after only a few moths of wearing them. They were not dropped, so I’m not sure why they’re cracked.

Look good
Style: Chic Metal Rectangular Shield, Color: Gold
Only 3 stars because they came with no case, just a soft bag. They look good though.

Nice Style!
Style: Chic Metal Rectangular Shield, Color: Gold
I had a pair of these years ago, and they were gold trimmed. The gold trim was around the outer frame of the glasses, and I really liked them and got many compliments on them. Those became scratched, and I was unable to use them so I did a quick search to find them again. These come and gold are rose, gold trim, and I ordered a pair of each expecting what I had before. I was sad to see that the quality didn’t seem to match what I had before, and the trim was on the inside instead of the outside, which I don’t understand. I also noticed that the ware seems to get looser the more times I wear them. They are harder to keep on my ears.

Comfortable and Cute
Style: Chic Metal Rectangular Shield, Color: Rose Gold & Rose
Very comfortable and doesn't slide down my nose. Got several compliments while I was on vacation. Even after wearing most of the day they didn't hurt my ears.
