If you notice a rash appears every time you wear your favorite shirt, you could have textile dermatitis. This skin allergy is a form of contact dermatitis where the fibers, resins, chemicals, and dyes in your clothing cause irritation.
Clothing allergies can happen with any fabric, but synthetics are more likely to cause the condition. You can start by swapping out polyester, rayon, spandex, or nylon for breathable natural fabrics like linen, cotton, bamboo, or silk. Wool is a natural fiber exception as it’s often a textile dermatitis culprit.
