Perfect size found for big kid
Size: 31W x 28L, Color: Medium Wash
Arrived quickly, fits perfectly, comes in many different sizes that works for youth that are in between kids and adult sizes. Also value for money. Did not shrink in washer/dryer. Material is comfortable.

The Best Black Slim Jeans for the Price
Size: 32W x 33L, Color: Black
This is the second pair I bought, this time in Black (32W x 33L). The size and fit are the same excellent slim cut as the medium wash version. The Black is a nice, solid color that looks semi-dressy.
The stretchiness is perfect—it makes these incredibly comfortable to wear all day. The material is soft and light for denim. For functionality, they are easily dressed up or down. As for long-term durability, based on my medium wash pair, they hold up very well, resisting bagging out in the knees and seat. Highly recommend this exact fit and material combination.

Sizing is bull.
Size: 36W x 34L, Color: Rinse, Size: 36W x 34L, Color: Rinse
I ordered the same size, same brand, 3 different colors and the dark one was the only one that fit. I returned the small ones and ordered another pair of the dark, same size, same brand, same color, same EVERYTHING, literally 2 days later and this is what I received. How is it the same but one is clearly at LEAST one size smaller? This is bull, I’m so mad. I’m not gaining weight, these should fit PERFECTLY (the larger one does). Ridiculous.

Great jeans at a great price
Size: 33W x 30L, Color: Blue Overdyed
These are great jeans and high quality. I compared them to some of my expensive jeans and found them nearly comparable. The slim cut works perfectly for me.
