Louis Shelley Suit Factory's custom-made suits undergo two "physical shrinkage treatments" before cutting the fabric. This not only enhances the fabric's elasticity and shape memory recovery but also eliminates internal stresses between fibers. Fabrics that have been through "physical shrinkage treatment" will naturally smooth out their creases after hanging vertically for 10-12 hours upon occurrence, thus avoiding issues with employees' suits being uneven.

Modern tailoring suits primarily use bonded interlinings, which not only simplifies the lining process and enhances production efficiency but also contributes to the stability of product quality. As long as the bonded interlining matches the fabric properly and the bonding process parameters are selected reasonably, the inherent quality of Beijing Louvre Sheli tailored suits can be guaranteed. Traditional tailoring suits still use black carbon interlining, mainly with hand-lining, allowing for personalized cutting and meticulous stitching based on the wearer's requirements and body type, ensuring the stability of the suit's quality. Currently, custom suits and international brand handmade suits still mostly opt for the traditional lining process.
