Loops were missing for belt. I returned for a different pair hoping it was a defect. Received another with the same problem. The denim ones have 6 loops. The white have only 4. So impossible to loop correctly. After I received the second pair they charged me for the ones I returned. So I paid for 2 pairs only kept one

High waisted, heavy duty, no stretch jeans

Size: X-Large, Color: Blue

I liked them, except they were high waisted which are not a good look for me.

Cute, comfortable and stylish jeans

Size: Small, Color: Blue

These jeans are so cute! They are on the thicker, stiffer size. I got a lot of compliments on the patchwork jeans. They did arrive with a very strong sort of chemical odor. I washed twice before I wore them.
