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!

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!
