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.
