Look for redness, scaly skin, or itchy areas. Sometimes they pop up within hours after you put on your clothes, or they may take days or weeks to appear. Some people can wear the same item for years before a rash breaks out.

Symptoms often begin in the folds of your skin or other areas that make contact with your clothes and what’s in them. That includes:

• The crooks of your arms;
• Behind your knees;
• Armpits;
• The groin;
• Any place where your clothing is tight.
