Using these Bowserween tank tops is as easy as slipping them on! They're super comfortable for everyday wear. When it comes to sizing, the men's and unisex ones go from XS to 2XL, while the women's are available from XS to 4XL. Make sure to pick the right size for a perfect fit. For washing, use cold water and turn the tops inside out. Wash them with clothes of similar colors. Only use non - chlorine bleach if needed. After washing, you can either hang them to dry for the best look or use a tumble dryer on cool or low heat. But remember, fabric softener can make the colors fade, so it's best to skip it. And don't try ironing or dry - cleaning these tank tops, as it might damage the fabric.
