When you get your 'Not Fast, Not Furious' men's t - shirts, you can wear them right away for a casual look. Just choose the size that fits you best, whether it's a regular t - shirt from S to 6XL or a premium one from S to 3XL. For washing, turn the shirt inside out and put it in the washing machine on a cold cycle with clothes of similar colors. Only use non - chlorine bleach if there are stains. After washing, it's best to hang dry the shirt to keep its shape and color. If you're in a hurry, you can tumble dry it on a cool or low - heat setting. Remember, don't use fabric softener because it can make the colors fade. Also, avoid ironing and dry - cleaning the shirts to keep them in good condition.
