Great quality
Color: Brown, Lens Width: 37 Millimeters
I normally like to try on sunglasses but these were a deal on the Prime days and I gave them a chance and am so happy I did! They fit really well being not too big and not too small, and they also aren't tight against my head. They came with a case to keep them from being scratched which I truly appreciate. Excellent value for the price.

Just order them!
Size: X-Large, Color: Brown Black
Absolutely dig these loose, lightweight, flowy cheetah print palazzo pants! I got the XL in brown/black and can't wait to wear them. They are true to size (I typically wear a 16 and have ample hips). Will pair with a more fitted tee, platform sandals a d a jean jacket. So cute and comfy!

Awesome pants.
Size: X-Large, Color: Brown Black
LOVE these pants and have gotten so many compliments. Cool and comfortable. Very wide leg - be prepared for snarky comments but WHO CARES? I say let the haters hate because clearly they are jealous of your amazing pants. The pants are very cute with a denim button down or an oversized tee and some sneakers. I am 5'9" and the pants are plenty long. Not too long to drag on the floor but right to the sole of my sneakers.

Run very big!
Size: Medium, Color: Grey
The pants are SUPER CUTE. The material is fine. My complaint is how BIG they are cut. I’m 5’5”, 165, tiny bootie, and large legs-i ordered a medium- they are so BIG, should have purchased a small but need to have them in 2 days so I will be altering them myself.
