Summarize this article in one sentence.
Tight clothes can cause chafing as your skin rubs against the fabric. It also causes you to sweat, which can make the chafing worse. Avoid wearing clothes that are resting directly on your skin. Wear reasonably loose-fitting clothes to avoid friction and give your skin time to heal.  Avoid tight belts, tight underwear, and clothes that cause you to sweat. All of these are keeping your skin from breathing and can make your chafing worse. In the winter, you may want to do the opposite. Looser clothes may trap your body heat and make you sweat more. Wear cotton whenever you can. Fancy polyester shirts and denim trousers may be tempting, but they can trap heat and cause you to sweat which can trigger chafing. Cotton dresses, shorts, and shirts are easy to find in a variety of styles as well. Giving your skin room to breathe is the best way to give the skin time to repair naturally. In general, you should always choose materials that feel good against your skin. Avoid any materials such as wool and leather. Many people chafe between the thighs when they’re running or working out. If this is you, pick up a pair of tight-fitting anti-chafing shorts. These shorts have padding for your thighs to keep the friction from doing damage. Since it’s hard to let this area breathe, this is probably the best way to handle the irritation. The minerals and oils in your skin transfer to your clothing after you wear it. When you re-wear clothing, you’re exposing your chaffed skin to those minerals and oils. This can irritate the skin and increase the amount of time it takes to heal.

Summary:
Wear loose-fitting clothing to keep your skin cool. Opt for clothes made of cotton or some other breathable material. Wear some anti-chafing shorts if the issue is with your thighs. Wash your clothes after wearing them once to avoid irritation.
