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.

Love these shirts
Size: Small, Color: Watermelon, Number of Items: 1
Love the fabric. They feel so much better than some of the other shirts I have. They’re thicker and just feel nicer. Love this color too. Got a small and also have another color in medium. Both fit, just depends on how casual I want to look. I’ll be getting more!

Nice Quality for the Price
Size: Large, Color: White, Number of Items: 1
I ordered a large and it was a little too big. I washed and dried it and it didn't shrink too much. It's very soft and feels nice. For the price it's better quality than expected. I am planning to order a medium which should be the right size. The large fits my husband perfectly.
