How to use: This t - shirt can be worn on its own for a casual look or layered over leggings for a more stylish outfit. Just slip it on like any regular shirt. Attention: When ordering, remember to size up if you want to layer it with leggings. Maintenance tips: Since the fabric has been laundered to reduce shrinkage, it should hold its shape well. Wash it in cold water and tumble dry on low to keep it in good condition.
