Once you purchase your suit, suit care should be on the top of your to do list. Few things to consider are: dry cleaning, tailoring, storage and moth protection.
Moth Protection - It would be a great tragedy if you wore a suit worth $1,000.00 only once and then found it had been eaten by moths the second time you wanted to wear it.
Suit Storage – You will wish to have your suit ready to wear at all times which means curled up in a ball under your bed is not an option.
Suit Alterations - Except you plan on staying the exact same size all of your life, you will probably need to find a good tailor.
Dry Cleaning - If you choose to just pop your suit in the washing machine, you can probably forget about ever being able to wear it again.
