Mistake (3.) Synthetic fabrics and silK
When it comes to material, experts agree that your personal preference can dictate the fabric—as long as you make sure the crotch is lined with cotton.
“Most of the underwear that’s available is fairly breathable,” says Dr. Dardik. “As long as they have a cotton liner where the vaginal area is, you’ll be fine.
But if you’re looking for optimal underwear conditions, steer clear of synthetic materials, and only wear silk on special occasions. “Silk and synthetic fabrics are not breathable, which increases the risk of moisture being trapped and retained, which can create a yeast or bacterial infection,”
says Dr. Moore.
