Our wardrobes constantly get refreshed with the latest fashion trends, but sometimes, it's what we wear below the surface that gets forgotten.

Every single one of us has that draw which is full of undies ... undies that we've had for quite some time, and still wear because they're super comfortable.

Well, you need to throw every single pair in that draw away!
