The Marvin mini skirt is responsibly crafted from pure cashmere & OEKO-TEX certified dyes only, with an uber-soft hand feel. It needs your gentle care and loves a wash. This style is machine washable at 30 degrees . If your washing-machine has a separate spin speed setting, choose 600 rpm (do not spin at higher speeds). If the 30° delicates/wool cycle of your washing machine is pre-set at 300/400 rpm, use this setting. Lay flat to dry. Enjoy for a lifetime.
