For the person, who is not acquainted so much about fabrics, usually suppose quality by the feel of fabric. The feel of denim fabric, which is smooth and has a little humidity, usually considered as made with good-quality cotton, whether the denim is raw. There are many processes in manufacturing, such as the customary way that is known as right-hand twill and left-hand twill, as well as there is ringspun, a double ringspun, broken left-hand twill, cross-hatch, double ringspun etc…
Moreover, there are other processes like stitching, accessorizing and others. There are chiefly two techniques to sew the side-seam – overlock stitch and open seams. In the open seam, the seams are taken at outer-side of the legs and then hard-pressed flat. Where as, in the overlocked stitch up is sewn the two pieces of fabric together.
The fact is, everybody wishes to have
just right pair of jeans that makes them look nice, but there is always price barrier. Thus understanding the quality prior to spending hundreds of dollars on a pair of valueless jeans is recommended.
