I once got dressed in a blue and white pinstripe dress that I thought read exactly like a crisp business shirt.
My husband took one look and asked why I was wearing a nightie.

Same garment, same morning, two completely different readings. It cost me $3, which is not the point, though it is never entirely not the point.
The point is that you cannot see your own signal. Which is precisely the problem with dressing for a new job, where the whole exercise is sending a signal to a room full of people you have not met yet.
Dress for the job you have just got
Not the one you left. This is the single most common mistake and it catches nearly everybody in a career change.
Whatever you wore at the last place became invisible to you. It stopped being a choice and became a habit. So you turn up at the new one in the old uniform, and it is either a little too formal, a little too relaxed, or simply a little off in a way nobody can name and everybody notices.
Corporate people over-dress for creative workplaces. They arrive in a suit and spend a fortnight feeling like a bank manager at a party.
Creative people under-dress for corporate ones, arrive on day one in something with personality, and are read as not quite serious before they have opened their mouths.
Neither is a taste failure. It is just carrying a habit across a border.
Read the room before day one
You can do almost all of this before you start, and almost nobody does.
Ask, but ask specifically. “Is there a dress code” gets you a shrug and the word “smart casual”, which means nothing on its own. Ask instead: what would you wear on a normal Wednesday? Put it to whoever organised your start date. It is a completely normal question and the answer is usually detailed.
Remember the interview. What was the person interviewing you wearing? What about whoever walked you out? That is real data and most people are too nervous to have registered it, so write it down now while it is still there.
Look one level up. Not at your peers, at the people a rung above the job you are taking. That is the register you are moving toward, and it tells you where the workplace’s idea of seriousness actually sits.
And look at photographs. Team pages, conference photos, anything public. Not for outfit ideas but for the overall temperature of the place.
The first fortnight
Day one: half a step smarter than you expect the room to be. Slightly overdressed reads as taking it seriously and is easy to dial back by Wednesday. Underdressed on day one takes a month to undo.
Wear something you have worn before. First day is not the day to discover that a new waistband digs in when you sit, or that a jacket is unbearable in a warm room. You have enough to think about.
Then watch, for two weeks. Who is dressed how. What the most respected people in the room wear. Whether Friday is different. Whether anyone actually wears the thing the policy describes.
And only then spend. Which brings me to the part that saves the most money.
Do not buy a work wardrobe before you start
People do this constantly and it is the single most expensive mistake in a career change.
You buy for an imagined version of the job, based on the job title rather than the room, and three weeks later you own four blazers for a workplace where nobody wears one.
Buy two or three things that get you through the fortnight. Wait on everything else until you have actually been there.

The money problem nobody mentions
A new job usually means a gap before the first pay lands, which is exactly when you feel you need clothes and exactly when you have least.
So here is the order I would go in.
Shop your own wardrobe first. Almost every wardrobe holds more work-capable clothes than its owner believes, particularly once things are recombined. That is the whole method in building outfits from clothes you already own.
Then alter, do not replace. A tailor is the best value in fashion. Trousers hemmed to the right shoe, a jacket taken in at the waist, a sleeve shortened: tens of dollars, and it transforms how senior something reads. Three alterations will do more than one new purchase.
Then buy one genuinely good thing. Usually a jacket, because it is what people see in a meeting and it does the most work.
And the rest can wait until you are paid. The op shops in the right suburbs and the outlets will cover the gap for very little in the meantime. A well-fitted three dollar dress reads better than a badly fitted expensive one, and I can promise you that nobody at work can tell.
A fortnight of outfits from very little
Because the practical question underneath all of this is usually how few things you can get away with while you work the place out.
Five pieces will cover ten days if they are chosen to combine rather than to be admired separately.
Two bottoms. Tailored trousers and a skirt or a second pair of trousers, both in the same neutral so every top works with both. Navy, charcoal or black, whichever suits your colouring.
Two tops that are not the same. One with a collar or some structure, one softer. Different enough that an outfit changes character when you swap them.
One jacket that fits properly. This is the piece worth the money and the alteration, because it is what people see when you stand up in a meeting.
Then rotate. Nobody is auditing your repeats in your first fortnight, and the people who would notice are the same people who dress in a rotation themselves.
Add a third top in week two, once you know whether the room is more relaxed or less than you thought. That is the first purchase where you actually have information.
And keep one outfit in reserve for the unexpected day: the client visit, the drinks, the senior person who turns up unannounced. One notch up from your normal, hanging ready, so you never have to solve it at seven in the morning.
The whole point of a small starting wardrobe is not minimalism for its own sake. It is that you are buying yourself two weeks of information before you commit any real money.
Fitting in, then being remembered
Both, in that order.
For the first month, let the clothes be quiet. You want people noticing your work, not your outfit. This is not an argument for dullness, it is an argument for timing.
Then add one thing that is consistently yours. A colour you wear often. A particular jacket. Serious earrings. One signature, repeated, does far more for being remembered than a wardrobe of different statements, and it takes the decision out of the morning.

The repetition is the point. People who dress memorably mostly wear the same handful of things in rotation. It reads as having a point of view rather than as having run out of ideas.
Looking more senior, specifically
This comes up constantly, usually from someone who has been promoted and feels they now look junior next to the role.
It is almost always fit. Clothes slightly too big read as borrowed, and borrowed reads as junior. A jacket sitting correctly on your shoulders does more for authority than any amount of expensive fabric.
It is also structure. Something with a defined line, a collar, a proper shoulder, a real waist, reads as more deliberate than something soft and draped. You do not need a suit. You need one structured element.
And it is fewer things. A smaller, more repetitive wardrobe reads as decisive. A busy one reads as uncertain.

Coming back to work after a break
A slightly different problem and a harder one, whether the break was parental leave, illness, redundancy or caring for somebody.
The wardrobe belongs to a previous version of your week, and often a previous version of your body. Opening it can be genuinely deflating, and the temptation is either to force the old clothes to work or to replace everything at once. Both are mistakes.
Start by separating what does not fit from what is simply out of date. They feel identical when you are standing there and they are entirely different problems. Things that do not fit can often be altered. Things that are dated usually cannot, and a surprising number of what people assume is dated is simply creased and unloved.
Expect your judgement to be rusty, because it is a skill and you have not used it daily for a while. Give yourself longer than you think in front of the mirror, and do not trust the first reaction.
And be careful about buying confidence. The instinct to arrive transformed is very strong after time away, and it produces the most expensive mistakes I see. Arriving looking like yourself, well put together, is a stronger position than arriving as somebody unrecognisable.
One good jacket, properly fitted, and clothes that actually fit the body you have now. That is nearly always the whole answer, and it costs far less than the wardrobe people imagine they need.
The mistakes I see most
Buying the whole wardrobe in week one. Covered above, and worth repeating because it is the expensive one.
Dressing for the job title instead of the room. Manager does not mean the same thing in two buildings on the same street.
Ignoring the shoes. People notice shoes at work far more than they admit, and a scuffed pair undoes a great deal above it. Clean them the night before.
Forgetting the building. Offices are heated and cooled to one temperature regardless of the weather outside, which in this city is its own problem. Something you can take off matters more than something warm. The full case is in dressing for Melbourne weather.
And dressing for who you were. The hardest one, especially after a long stint somewhere or a break from work. The wardrobe belongs to a previous version of your week, and it takes a deliberate decision to stop dressing for it.
The short version
- You cannot see your own signal. Ask somebody who can.
- Dress for the job you have just got, not the one you left.
- Ask what people wear on a normal Wednesday, and look one level up.
- Day one: half a step smarter, in something you have worn before.
- Watch for a fortnight before you spend anything.
- Shop your own wardrobe, then alter, then buy one good jacket.
- Quiet for the first month, then one signature you repeat.
- If you look junior, it is almost always fit.
Wardrobes do not travel between jobs as well as people expect, which is why a start date fills my diary almost as reliably as a wedding. Two hours with a personal stylist in Melbourne is $299 and works entirely from the rail you already own, which matters when the first pay is still a fortnight away. Leave the shopping until you have read the room, then a Half Day of personal shopping in Melbourne is $399.
Now go and work out what people there wear on a Wednesday.
And now you’re Looking Good Girls.
