wrong fit - small and doesn't match original - doesn't meet description
Size: 36W x 29L, Color: Black
DKNY must watch who produces their brand. Have a few pairs and they are made in Bangladesh and fit amazing. Just ordered this pair and it's not even close to how it should fit. Very small and waist band doesn't stretch at all and made in China.
