Great quality for the price!
Color: Apricot, Size: Small
Great palazzo pants! I was looking for something to wear in Florida to a graduation but did not want to be too hot. These pants are versatile and very flattering. So comfortable as well and no wrinkles! The length was perfect for me at 5'2" and they wash very well. I purchased slip shorts to wear underneath to avoid the dreaded panty line / crease, etc. and the slip shorts smooth everything out & make you look seamless!

So great, that I own 4 pairs of these Sampeel pants!
Color: Pattern Leopard, Size: Large, Color: Pattern Leopard, Size: Large
I own 4 pairs of these pants because I love them so much! I receive many compliments when I wear them. They are stylish, comfortable, and a great thin material that keeps you cool while looking professional. I am 5" tall and can wear them with heels without needing them to be hemmed (which is unusual for me when ordering pants). They have an elastic waist band with drawstrings so I can wear them while losing weight, they don't wrinkle easily, and they have pockets! Great pants for a great price! I will continue to purchase more throughout the summer.

The good with the bad
Color: Pattern Kah, Size: XX-Large
Photos in listing depict a LINEN pant - in the close up's you can clearly see a linen/cotton like material. To my surprise, these pants are a silky, polyester material. There is NO stretch - I am glad I purchased a size larger than what I consider my " roomy " size. These style is also depicted as a beige and black color pattern, they are more of a light mauve color out of the packaging. Took a steamer to them to get the wrinkles out. Suitable for tall girls ( I am 5'9 ) and wearing them with 3 in wedge. They are cute - dressy enough for a business casual office setting or a date night. Probably not the best for hot humid weather as they are not breathable.

Incredibly comfortable and perfect for summer!
Color: Pattern Leopard, Size: X-Large, Color: Pattern Leopard, Size: X-Large
I have to admit, I was a little skeptical about these pants at first. When I initially opened them, they didn’t feel like they had much stretch, and the fabric felt a bit cheap to the touch. However, once I actually put them on, my opinion completely changed! They are so incredibly comfortable and have a great, effortless drape. The material is lightweight and breathable, making them absolutely perfect for warm summer days. They are easy to style (looked great paired with a simple tank and a denim jacket!) and feel wonderful to move around in. I am so glad I gave them a chance—I would definitely purchase these again!

Cute and comfortable
Color: Pattern Leopard, Size: Medium
Comfortable and cute. A little long but still wear them with no issues. The material is light but synthetic so not really breathable. I foresee wearing them often.
