To use this tee, simply put it on like any other shirt. It's great for casual outings or just relaxing at home. When it comes to washing, follow the regular care instructions for cotton clothes. Use a gentle cycle and mild detergent. Hang it to dry to prevent any possible shrinkage, although it's pre-shrunk. Be aware that there might be some shade variations due to the pigment dye process, which is completely normal. This is a high - quality and eco - friendly tee, so take good care of it and it'll serve you well for a long time.
