Wide leg snatched waist band
Size: X-Large, Color: Brown Black
These pants are perfect. The material is thin but not see through. They are breathable and are truly wide leg and made well for us tall girlies. I'm 5"8 and I usually wear 16/18 pants. I have a short torso, all legs and these pants fit me perfectly. The waist band is a nice snatch for a body suit top. I'm happy.

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.
