When it comes to dresses from Theory, Lyst has you covered. The brand’s commitment to expert craftsmanship endures, with each piece using materials such as cotton. Available in a variety of colours and designs, Theory's dresses will work as well with your weekday workwear as they will with more casual looks. Combining a minimalist design with expert craftsmanship, it’s easy to see why this collection is so popular. Cotton dresses need to be cared for properly to ensure they stay looking their best. To ensure cotton remains in perfect condition for years to come, we suggest always checking the label to ensure no specific care instructions are required. As cotton lacks natural anti-bacterial and odor-resistant properties, it requires more frequent washing. We recommend washing at a cool temperature that is no more than 30°C, and then gently reshaping as soon as it comes out of the wash. Avoid tumble drying, instead, air dry away from direct heat such as sunlight or a radiator. Shop the latest women's designer dresses from Theory at Lyst now.
