Due to its fiber composition, most crepe garments are “Dryclean Only.”
Crepe is extremely susceptible to shrinkage when exposed to moisture. This is especially true for crepes that contain wool, silk, or rayon. Home stain removal on crepe garments may also result in localized shrinkage.
If the care label says it is safe to wash the garment, use cool water, rinse thoroughly, and extract lightly. Air dry. Do not tumble dry.
Finishing usually requires blocking the fabric to get it back to its original shape.
