Stretchy Comfort
Size: 34W x 30L, Color: Dark Blue
Jeans were as described and quite stretchy which makes for a good fit. The size was as described. The quality was as good as the Big Box Stores for less money. The material is thinner than traditional western style baggy jeans but should still wear well. Nice traditional blue jeans color.

Fit and color with affordability
Bought for my dad after he lost weight. He is 88 and they run true to size with stretch for him to put on by himself. Very satisfied with color and fit. They are not heavy like normal jeans which is a plus for our situation

Absolutely adorable
Bought for my twins, in two different colors, absolutely frickin adorable. A little too big for them, but they're small for their age. Wish it came with a shirt too, but we just bought them separately. Durable and well made. Definitely worth it.
