More like every 2-3 days and how bad is it if I don't change my cloths everyday. I just don't see the point in it til after I take a shower. My mother's house use to have septic problems which ment we couldnt use the shower everyday only every other day. This is my confession. And know I don't stink you can live without a shower for a day or 2. Its actually bad for you're skin to shower everyday.
