You probably don't need us to tell you that clothes can smell a bit funky sometimes. It might be because you have no choice but to dry clean clothes indoors in a humid environment or because you shove them at the back of your old dresser. Whatever the case, you could wash them again to get rid of the smell - but that's not very budget-friendly. So, you could use a bar of soap instead.
All you need to do is wrap a bar of soap in a thin towel or napkin and then place it alongside your clothes in the drawer. If you choose one with your favorite scent, it'll work wonders.
