To use these tank tops, simply put them on and enjoy their comfort. When it comes to washing, toss them in the washing machine on a cold cycle, turn them inside out and wash with similar colors. Only use non - chlorine bleach if needed. After washing, hanging them to dry will keep them in top shape, but you can also tumble dry on cool or low heat. Just don't use fabric softener as it can fade the colors. And remember, don't iron or dry clean these tank tops to maintain their quality.
