There are guys who will dry clean their suits on a weekly basis. The thinking behind this is correct, at the end of the day you want to show up to the office looking clean and fresh. But dry-cleaning your suit to often will wear away the natural fibers and take some years off. If you suit is clearly dirty then take it to the cleaners, otherwise, use a lint roller or spot clean with water and a soft towel on small stains will suffice. So no more than once a month.
If you want to prolong the life of your suit, get a steamer. Never use a normal dry iron directly on your suit as it will burn the fibers and add a sheen to the material. But, if your steamer isn’t doing the job you need, bring it to the cleaners and ask them to press it.
Your suits should be hung up in your closet. To make sure your suit maintain its form, we advise using wood or plastic hangers with rounded edges. These offer a more natural shape that fills out the shoulder nicely, and allows it to sit and drape nicely. When it sits for a day or two, the suit will naturally go back to its original drape.
