To achieve a true slouchy effect it's suggested you order a size up.
The design is printed on the shirt through a process known as flex printing, which is a method in which the design is printed on matte foil and then heat-pressed on the product resulting in a print that is highly durable and can withstand many washes.
T-shirts should be washed inside out and set on a gentle machine cycle in cold water. When drying, tumble dry on low heat. To avoid shrinkage lay flat to dry. To maintain the life of the design, t-shirts should be ironed inside out on a low heat setting without the use of steam. This step also aids in refreshing the colors in the design. Dry cleaning is not recommended.
