Design: SMFK VINTAGE Retro Collection utilizes vintage-style materials and post-processing techniques such as garment dyeing/color blending/salting/stone washing to present the retro texture of the clothing. High-density woven fine twill workwear cotton fabric is used to create retro work pants with a low-saturation, faded texture. After sewing, the fabric undergoes garment dyeing (multiple water dyeing), followed by salt blending (color blending) and bleaching (bleaching to create a matte velvet and gray tone on the surface), achieving a traditional dyeing and long-lasting retro texture. In terms of design, SMFK combines CARGO work pants with athletic pants, continuing the exterior patch pockets and drawstring cuffs design of workwear and retro military uniforms.
