Always carry a foldable rain cover in your bag so that if there is any sudden downpours your clothes and other things are protected.
Prefer synthetics like polyester or nylon that dry much faster than any other fabric during monsoon.
Don’t worry even if your clothes have soaked rain then quickly steam them as it helps to remove moisture and damp smell.
During monsoons keep a drying rack under a fan or under a ceiling fan which will help the clothes to dry faster.
During rainy seasons when you are washing clothes add a spoonful of salt while rinsing to prevent that musty smell from clothes.
During monsoon, always carry a spare top or shirt with you in a waterproof pouch in case the skies surprise you.
Use iron to quickly dry collars, sleeves, or hems that do not air-dry completely during rainy seasons.
