To use this tee, simply put it on and enjoy its comfort all day long. When it comes to washing, use cold water and mild detergent to keep the colors and fabric in good condition. Avoid using bleach as it may damage the low - impact dyes. Hang it to dry or use a low - heat setting in the dryer to prevent shrinkage. Since it's made to order, please be patient during the 7 - 10 business day processing time. And don't be surprised by the shade variations in pigment - dyed tees, as it's a natural part of the process.
