It is not necessary to dry-clean your suit after every use. Wool is naturally odor-resistant. In many cases, your suit may only need to be dry-cleaned two to three times a year.
Dry-clean all the matching pieces of your suit at the same time to prevent uneven color fading from the dry-cleaning process, which could leave you with non-matching pieces.
Enjoy your new suit. These garments are meant to last a lifetime!
