Wanted to like them
Special Size: 6" Inseam Contrast Trim without Pockets, Size: Medium, Color: Flamingo Pink/White
These are very cute but no compression at all in the waist. Even if I was to size down I wouldn’t feel comfortable working out in them. They would be too loose. Maybe for leisure they’d be okay but for CrossFit or running or moving a lot, I wouldn’t bother.

Nice fabric
Special Size: 7" Inseam with Pockets, Size: X-Large, Color: Taupe
These are well made. The fabric is perfect! Not thin. I was disappointed that I ordered a size that was too large. I had to return. I need to get updated body measurements before reordering.

Not great but not terrible
Special Size: 7" Inseam without Pockets, Size: XX-Large, Color: Navy
It fits fine, it’s pretty loose on the torso portion though so it doesn’t stay up well. I will not be purchasing again but I didn’t return it.

Best tote bag ever!!
Size: One Size, Color: Black
It's big and sturdy enough for my laptop and other stuff. The best part is that it's pretty and looks great. It's not heavy and it's comfy. You can carry it by hand or on your shoulder. Everyone always asks me where I got it. It's totally worth it. I love Amazon, and thanks for the awesome product.
