No need to wash your garment after every wear! And no need to dry clean!
Steam regularly for refreshing, and spot clean for any stains. When you do need to wash your garment, I recommend hand washing with lukewarm water and a drop of detergent. If hand washing is a terrifying venture, you can also machine wash on the delicates setting in a delicates bag, on cold. Make sure to keep any hook and eyes fastened to avoid any accidental holes or tears during the spin cycle.
Once washed, by hand or machine, lay flat to dry. To preserve the garments shape and original color, avoid hang drying outside in the sun.
