Bleach Dobby Cotton Stretch Worker Coat Bleach GrayDESCRIPTION D. HYGEN [SADDAM TEISSY] 2022 Spring Summer Collection. This item is made of stretch cotton fabric with a dobby weave like an embroidery. C # BLEACH GRAY has undergone a super bleach treatment after a sulfide dyeing. The sulfurous black on the seam and the valley of the fabric gives it a rough look. C #BLACK is reaction dyed. The pockets and stitchwork are inspired by heavy duty workwear and the finished product gives a strong impression.
