Superb Texture Review by Nishant
The texture of the secret denim is superb. The beige weft shines through the indigo warp. Cant wait to see how it fades. The fitting of the 288zr is spot on. Though it is regular straight but sizing down ( i bought size 32 one wash wich measured 32.7 inches) when my actual waist is 34 inches. This resulted in a slim straight fit. The waist stretched out to 34 from 32.7 in one wear itself. (thank you Peter for your spot on advice.) (Posted on 2/27/17)
