Update your closet today with Theory. Shop all the latest designer knitwear in our selection. Each piece is crafted with care using materials like wool, and every detail is carefully considered. Everything by Theory will seamlessly integrate into your existing wardrobe. Theory continues to impress with its wide selection of coveted pieces that always feel modern. Once you’ve invested in a wool item, keeping it looking its best is a must. Ensure your wool stays in its most beautiful condition by cleaning and storing it properly. We would always recommend checking the garment’s care label to ensure the cleaning method you plan to use will not cause shrinkage. One of the worst things you can do to wool garments is to wash them in hot water or tumble dry, as high temperatures can cause the fabric to shrink quickly. Most wool clothing can also be dry cleaned safely. Some wool pieces, such as a suit, blazer or coat, would benefit from spot cleaning. Otherwise, most wool can be either hand washed, or washed in the machine on a gentle cycle of 30°C or less, using a mild PH neutral detergent and turned inside out first. To reduce the risk of shrinkage, soak your wool item in cold water before machine washing. Never tumble dry wool, instead dry flat away from direct heat or sunlight. Most wool knitwear, no matter how good the quality, is prone to pilling. Gently pass a pilling comb over the fibres to remove any of the bobbles.
