The biggest problem with tight pants, especially jeans, is that they can rub up against your body and cause irritation.
This can lead to symptoms that look very similar to an infection, like itchiness, redness, and irritation. Some people may mistake this irritation for infection, which is why it’s important to see your gyno instead of trying to self-treat.
Chances are slim, though, that your skinny jeans themselves will cause an overgrowth of yeast or bacteria. Theoretically, however, they could be one small part of the larger equation. They decrease breath ability, helping trap heat and moisture in your vagina, which can promote an environment where yeast and bacteria thrive. It makes sense. But what you have on underneath those jeans is more important.
For women with chronic yeast or bacteria infection, something is clearly disturbing the pH of the vagina, it could be the detergent they’re using or underwear they’re wearing. Underwear made of synthetic materials traps moisture, decreasing the air flow in that area. When you pair the two together, it could potentially make a greater impact than either factor itself. (Underwear made of wicking materials, like polyester, is good for a very sweaty workout, but not necessarily everyday use.)
