The first thing is to stop wearing the item that bothers you. Your skin will most likely clear up within a few weeks. You can also:

• Wear natural fibers and loose clothes to help cut how much you sweat.
• Choose light-colored garments with less dye in them.
• Avoid items labeled “wash separately.” They’re more likely to bleed dye.
• Don’t wear clothes that say wash and wear, permanent press, no-iron, or dirt repellent. They’re likely to have chemicals that irritate your skin.
