Remember all our previous talk about keeping sores dry during an outbreak of herpes? Much of that has to do with the kinds of clothing you wear. Breathable clothing goes a long way toward shortening the symptoms of an outbreak [source: ASHA].
When dealing with sores, remember to wear loose-fitting clothing [source: NLM]. This allows air to circulate and keeps sweat and moisture away from the affected area.
Cotton is the best option when choosing breathable underwear. Avoid synthetic fabrics or silk underwear until the outbreak has passed. Also, don't wear tight-fitting pants, whether made of cotton, polyester or any another fabric [source: NLM].
