There is a formal stretch of the year coming, and for most people that means the same jacket is going to be worn three or four times across a couple of months. The instinct after each evening is to send it off to be cleaned, on the grounds that it has been worn and therefore must need it. That instinct does more harm than it prevents. A tailored jacket has a finite number of full cleans in it, and each one uses some of the structure up. Knowing what actually needs removing, and what simply needs time and air, is what keeps one looking right.
Why cleaning less often is better
A tailored jacket is not one piece of cloth. It is an outer shell, a canvas or fused interlining, shoulder padding, a lining and a great deal of stitching, all of which move differently when they are wetted with solvent and then dried. Repeated cleaning shrinks some of those layers slightly more than others, and the result is the faint rippling across the chest and lapel that makes an older jacket look tired even when the cloth itself is sound.
The cloth loses something too. Worsted wool carries a small amount of natural oil and a finish applied at the mill, and both give the fabric its handle and its drape. Solvent takes them out along with the soil. One clean makes no difference you could name. Six or seven cleans leave a jacket that feels papery and hangs flatter than it did, which reads immediately as shoddy even when the tailoring underneath is good.
So the sensible standard for evening wear is not a schedule but a trigger. Clean it when there is something on it that will not come off any other way, or at the end of the formal run before it goes into storage for the rest of the year. Between those points, air it, brush it and deal with individual marks where they sit.
What an evening actually leaves behind
Most of what a jacket collects in a night is not soil at all. It is moisture, from the body and from a warm room, carried into the fibre along with whatever volatile compounds were in the air. Wool takes on a remarkable quantity of water vapour, close to a third of what the garment weighs, without ever reading as wet to the hand, and gives it all back once the surrounding air is drier. Almost everything you can smell on a jacket the morning after leaves with the moisture.
That is the mechanism behind airing, and it is why airing works so much better than people expect. Hang the jacket where air moves around it, not in a packed wardrobe, and leave it a full day before it goes away. The lining dries, the wool releases what it absorbed, and the creases that formed while sitting relax under the weight of the cloth itself.
What does not leave with the moisture is anything solid or oily. Dust settles into the surface and needs a brush. Skin oil transfers at the collar and inside the cuffs and builds up invisibly over several wears before it shows as a darker band. Food and drink go in and stay in. Those three are what a clean is actually for, and only the last two really argue for a full one.
The satin lapel and how it goes dull
The facing on a dinner jacket lapel is usually satin or grosgrain, and satin is not a fibre but a weave. In a satin the warp threads pass over four or more weft threads before dipping under one, so the surface is almost entirely made of long, unbroken lengths of yarn lying parallel. Light hits those parallel floats and reflects in one direction rather than scattering, and that is the whole of the shine.
It follows that anything which disturbs the floats destroys the effect locally. Pressing the lapel flat crushes the floats down against the cloth beneath and flattens their curve, and the reflection goes from liquid to dull grey in that patch. Rubbing at a mark does the same thing by lifting fibres out of the floats. Once a satin facing has been crushed or roughened, there is no reliable way of putting it back.
Which means the lapel is the part to leave alone. Do not iron it. Do not scrub it. If it needs attention, steam held well clear of the surface will lift a crease without touching the floats, and a soft brush drawn along the direction of the weave rather than across it will take dust off. Anything more than that is a job to hand over rather than attempt at the ironing board.
Marks that will not wait
Two kinds of mark get worse with time rather than staying put. The first is anything with sugar in it. A clear spill dries invisible, then oxidises over weeks into a yellow-brown patch that has effectively become a dye. The second is body salt at the collar and underarm, which is mildly acidic, draws moisture from the air and slowly weakens wool at the exact points that get the most flexing.
Both argue for dealing with the jacket soon after the event rather than hanging it up and forgetting it until the next one. Not because there is any hurry in the ordinary sense, but because the chemistry keeps running while the garment sits in the dark. A mark that is still fresh is a different problem from the same mark six weeks later.
What not to do is almost more important. Water on a wool dinner jacket leaves a ring, because the water carries dissolved soil outward to the edge of the wet patch and deposits it there as it dries. Rubbing with a napkin felts the surface and polishes the fibres. Lift what is sitting on the surface with something absorbent, blot rather than rub, and leave the rest to someone with solvent.
Hanging and storing between wears
The hanger does more work than anything else. A jacket carries its weight through the shoulders, and a thin wire or plastic hanger concentrates that weight on two narrow points, which over a season pushes a bulge into the shoulder padding that no amount of pressing removes. A broad wooden hanger that follows the curve of the shoulder spreads the load the way a body does.
Empty the pockets before it goes up. Anything left in an inside pocket pulls the front of the jacket out of line, and because the cloth is hanging under its own weight for weeks at a time, the distortion sets. The same goes for a wallet carried through the evening, which is why the breast pocket of an old jacket often sits open when the rest hangs flat.
For storage between the formal months, use a breathable cotton cover rather than the plastic sleeve a jacket comes back in. Plastic traps the moisture the wool is trying to release and holds it against the cloth, and wool held damp in the dark develops a stale smell and, in time, marks. Give the jacket its day of air first, then cover it, then leave it somewhere with a little space either side.
Formal wear in a Tempe wardrobe
Tempe is dry for most of the year, which is largely good news for tailoring. Wool releases absorbed moisture readily in dry air, so a jacket hung out overnight recovers more thoroughly here than it would somewhere humid, and the stale smell that comes from damp wool is rarely the problem it is elsewhere. Airing genuinely does most of the work in this climate.
The trade is dust. Fine airborne dust settles into the surface of a dark worsted and sits in the spaces between the yarns, where it reads as a greyish cast rather than as visible dirt. A brush is the right tool, drawn downward in short strokes so the bristles lift particles out of the weave rather than pushing them further in. Do this before the jacket goes into its cover, not after.
Heat is worth a thought too. A jacket left in a warm car for an afternoon is being pressed, because heat and the weight of its own folds are two thirds of what an iron does. Creases set that way take a long hanging to fall out, and on a satin facing they may not fall out at all.
For the rest of the wardrobe
Formal wear is the part of a wardrobe that should be handled least, but everything worn around it is ordinary laundry. Shirts, trousers, the coat that goes over the top. Our machines take proper loads at settings you choose, so a run of shirts can go through on a gentle cycle without sharing a drum with heavier things.
The machines at our self-service laundry on East Broadway Road give you enough drum sizes to keep delicate shirting away from towels and denim, which matters more than most people think, and there is space to hang things straight out of the wash rather than folding them into a basket damp.
Our machines and the store are cleaned daily.
Our wash-dry-fold service covers the everyday laundry.

The short version
A dinner jacket does not need cleaning after every wear, and cleaning it that often will age it. Most of what an evening leaves behind is moisture, which a full day hanging in moving air removes on its own. Brush the dust off, deal with spills before they oxidise, and leave the satin lapel alone, because pressing crushes the weave that creates its shine. Clean it properly at the end of the formal run.
