Using these Trheewood tank tops is as easy as putting on any regular top. Just pick the right size for you, whether you're a man or a woman. For men and unisex styles, sizes range from XS to 2XL, while women's sizes go from XS to 4XL. When it comes to washing, always use cold water and turn the top inside out. Wash it with similar colors to avoid color bleeding. Only use non - chlorine bleach if really needed. After washing, it's best to hang dry. But if you're in a hurry, you can tumble dry on cool or low heat. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these tops, as it may damage the fabric.
