When you hear wash a suit, the process of cleaning a tailored jacket and trousers made from wool, polyester, or blended fabrics. Also known as suit cleaning, it’s a topic that confuses even people who wear suits regularly. Most folks assume dry cleaning is the only way—but that’s not always true. In fact, washing a suit the wrong way can shrink it, ruin the lining, or kill its shape. But washing it right? That’s how you stretch the life of your suit by years.
Not every suit needs the dry cleaner. A wool suit, a common fabric for tailored clothing, known for its natural breathability and resilience can often be spot-cleaned or gently hand-washed if it’s a blend with stretch. But a dry cleaning suit, the traditional method using chemical solvents instead of water to clean delicate fabrics isn’t always the answer either. Overdoing it strips natural oils from the fibers, making the fabric brittle. You don’t need to dry clean after every wear. Most experts agree: if your suit doesn’t smell, stain, or look wrinkled, just brush it off and hang it up. A good suit brush and a steamer do more than a trip to the dry cleaner.
What about machine washing? Only if the label says so—and even then, use cold water, a gentle cycle, and a mesh laundry bag. Never toss a suit in the dryer. Heat is the enemy. Same goes for hot water, bleach, or harsh detergents. Even the hanger you use matters. A padded hanger keeps the shoulders from sagging. And never leave a suit bunched up in a gym bag after a long day. Let it breathe.
There’s a reason your grandfather’s suit still fits. He didn’t wash it every week. He aired it out. He brushed it. He knew when to leave it alone. Today’s suits are made better, but people treat them worse. You don’t need to spend $50 every time your suit gets a little dusty. You just need to know what to do—and what not to do.
Below, you’ll find real advice from people who’ve been there: how often you can wear a jacket before it needs cleaning, what fabrics handle water best, how to fix a stain without ruining the whole piece, and why some suits should never see a washing machine. No fluff. No marketing. Just what actually works.
