How to use: You can wear these tank tops on casual days, under a shirt, or for workouts. They're suitable for both men and women. Sizing is available from XS to 2XL for men's and unisex styles, and XS to 4XL for women's. Just pick the size that fits you best. Attention: Don't use fabric softener as it can make the colors fade. Also, avoid ironing or dry - cleaning these tank tops. Maintenance: When it's time to clean, machine wash them cold and turn them inside out. Wash with clothes of similar colors. Use non - chlorine bleach only if really needed. After washing, hanging them to dry is the best option. But if you're in a hurry, you can tumble dry on cool or low heat.
