Wool items are a great investment, and it pays to care for them properly. Well cared for wool dresses will last longer, we advise always following the washing instructions found on the item’s care label. As the material is prone to shrinking in hot water, always wash in cold or low temperatures. Some wool pieces, such as a suit, blazer or coat, would benefit from spot cleaning. Hand washing is often the best and safest method, as long as a mild detergent and cool water is used. If you really want to use the machine, check that the wool item is not dry clean only and place in a mesh laundry bag before selecting a cycle designed for delicates. To minimize the risk of shrinkage, it is advised to soak in cold water before you put in the machine. Avoid the tumble dryer, as air drying flat is the best and safest method. To remove wrinkles, steam or iron on a low-heat setting with a pressing cloth between the wool and the fabric. Theory's collection of dresses is all you need for the new season.
