What do people get wrong about looking after a suit?
This answer is a draft. It stays unpublished until legal review and source verification are complete.
Wearing a suit every working day is deeply rooted in Japan, so a good deal of know-how on making a suit last has built up. Abroad, the recurring questions are "how often should I dry-clean it?" and "is it fine to wear the same suit every day?".
Everyday care
| When | What to do | Why |
|---|---|---|
| After getting home | Jacket on a thick, shaped hanger; trousers on a clip hanger or one that grips the hems. Brush with a clothes brush, top to bottom | Removes dust and pollen, settles the fibres |
| Overnight | Air it in a well-ventilated spot out of the sun (don't put it straight in the wardrobe) | Lets sweat and moisture out. Wool absorbs moisture |
| Rotation | Don't wear the same suit two days running. Rotate 2–3 | Wool fibres recover their shape and spring in 1–2 days |
| Creases | Hang it in the bathroom for 1–2 hours (steam), or hold a garment steamer just off the fabric | Moisture lets wool fibres relax back |
| Trouser crease | Iron with a pressing cloth on medium (two dots), with steam | Prevents shine |
| Cleaning | Once or twice a season, and before storing. In a sweaty summer, ask for a "sweat removal" (汗抜き) or wet clean | Dry-cleaning cannot remove sweat (water-soluble) |
- Most suits are wool (or a wool blend), and the care label mostly reads "do not wash at home; dry-clean (P)". A "washable suit" carries a machine-wash symbol and can be washed at home.
- Shine is where friction has flattened the fibres (see the ironing article). It appears on the elbows, knees and seat. Steaming from a distance and lifting the fibres with a brush can make it less noticeable.
- Storage: a non-woven garment cover, moth repellent placed above the suit, plastic dry-cleaner's cover removed. Moths eat wool.
[Verify] Check the meaning of the symbols against the Consumer Affairs Agency's "Care labelling" page. Care frequency is based on general guidance from the textile and dry-cleaning industries.
Misunderstanding 1｜Wearing the same suit every day is fine
Wool needs 1–2 days to recover. Worn day after day, the knees and elbows bag out, creases stay, and the suit's life shortens. Rotating 2–3 suits is the basis of a long life.
Misunderstanding 2｜The more often you dry-clean, the cleaner it is
Dry-cleaning strips oils; repeated, it dulls the fabric. Once or twice a season; day to day, brush and air.
Misunderstanding 3｜Dry-cleaning removes sweat
Dry-cleaning (solvent) suits oily dirt; sweat (water-soluble) stays behind. At the end of summer, ask for "sweat removal" (汗抜き, ase-nuki) or wet cleaning.
Misunderstanding 4｜Iron the creases out
A hot iron directly on wool causes shine. Use bathroom steam, or a steamer held off the fabric. If you must iron: pressing cloth, medium heat.
Misunderstanding 5｜A wire hanger is good enough
The shoulders lose their shape and the jacket gets hanger marks. Use a thick wooden or plastic hanger that matches the shoulder width. Hanging trousers by the hems with clips helps the knees recover.
