“One-hundred-percent cotton is always best, especially during menopause, since it can prevent friction that can worsen vaginal dryness,” says Erica Montes, MD, board-certified ob-gyn and adviser for women’s health and wellness brand pH-D Feminine Health. You can shop for blends, but the minimum amount of cotton should be at least 90% for breathability and comfort, says Dr. Grover. (Almost all of the undies in this story are.)
There are certain people who benefit from wearing cotton underwear more than others. “For a person who has never had vulvar concerns, irritation, or infections, I recommend they wear what makes them happy,” says Dr. Ridgeway. “But for those with irritation, itching, discomfort, or a history of infections, I recommend cotton because the vulvar skin is delicate and vulnerable to irritants and allergens.”
Dr. Grover also notes the American College of Obstetricians and Gynecologists recommends that women with vulvodynia (persistent irritation of the vulva) wear 100% cotton women’s underwear to help relieve symptoms.
