9 Dressing Rules Every Female Founder Should Know

How you dress decides whether people trust you with their money, their time, and their business, often before you speak. These nine rules cover the established power look, fabric over brand, dressing slightly above the room, tailoring, shoes, makeup, lingerie, your colour season, and a signature look. Together they make you read as the leader you are.

You can have the best offer in the world and still lose the deal to somebody who looks better. Nobody will say it to your face, but how you look makes people either say yes or hesitate, and it shapes whether they trust you with their money, their time, and their business.

Here are nine dressing rules that change how seriously you are taken, and therefore how well your business does.

Should you avoid looking too feminine at work?

As a woman in business you are often undervalued by default, because you look young, or kind, or simply because you are a woman, so your outfit has to compensate for the authority you are not given automatically. If you already read as nice, pretty, or helpful, your clothes should not echo that. Avoid flowers, bows, and anything preppy, because warmth plus girly, approachable codes makes you look like you have soft boundaries, and soft boundaries read as negotiable prices, timelines, and scope. Adding sexiness compounds it, because women are already sexualised by default, and the Madonna-whore dynamic means men respect women they sexualise less. The fix is to convey power, but the right kind. Avoid dominating power, huge shoulders, a snatched waist, pointy shoes, towering heels, heavy makeup, long nails, which reads as insecurity rather than strength.

Aim instead for what I call an established power look: classic structure plus approachability. There are two kinds of authority, dominance and prestige. Prestige does not defend its boundaries harshly, because everything it embodies already expresses them, and that quieter, untouchable register is far easier for others to respect as a business peer.

Should you invest in the fabric or the brand?

Fabric, every time. People see only the face value of what you wear, not its price or its label. I once spent 420 euros on a shirt I loved, only to find it was extremely transparent, and when I asked my Instagram followers to guess the price, almost no one imagined it cost that much. Worn to a client meeting, it would have made me look like I was struggling. You cannot trust a brand or a price to guarantee quality: at a prestigious Paris department store, even high-end labels were selling transparent cotton and pieces blended with plastic for thousands. Never invest in anything blended with plastic, polyester, or polyamide. It looks cheaper, lasts less, and gives you no return compared with fully natural fibers.

Logos work against you too, because flaunting them subconsciously signals you need to prove your worth. If you love a brand, keep visible logos to one discreet placement, which says you can afford designer without needing it to feel worthy.

How dressed up should you be for the room?

Dress as if you were the most important person in the room, even before you feel like it. Early on you may have dressed to look approachable, but for your business to evolve you have to visually evolve first. Upgrading how you look attracts clients currently out of your league, because the moment you change your visual codes is the moment they start seeing you as a peer rather than someone beneath them. The rule of thumb is simple: your outfit should always slightly exceed the formality of the room. Underdressing reads as indifference, and overdressing reads as trying too hard, so the sweet spot is just above the room.

At an entrepreneurs' breakfast I wore a shirt, heels, a tailored trench, and a classic bag, with black barrel jeans for a touch of ease, so I read as serious without taking myself too seriously. The jeans did the softening; everything else did the work.

Why does tailoring matter so much?

Tailoring is the most underrated investment in your wardrobe, because how a piece falls on you says everything about your attention to detail. The classic landmarks are precise: the sleeve stopping at the wrist, the top ending at the waist, and trousers falling at mid-ankle. The current oversized trend works against you. It exists mostly because looser garments fit more body types, which lets brands produce fewer sizes, but oversized fits most people poorly. If you want to look like the entrepreneur who is succeeding, and attract clients out of your league, put real emphasis on tailoring and send the ill-fitting, oversized pieces to the giveaway bag.

Make tailoring part of the cost of any piece worth owning. It is built into the wardrobes I create for clients, because no wardrobe is truly impactful without it.

How should you use your shoes?

Shoes tell a story of their own through colour, shape, and the height and width of the heel, which makes them the easiest way to re-dress for different rooms in one day. If you have a client meeting, then a podcast, then a cocktail, you do not need to change your base, only your shoe. Wear a classic, understated shoe for the meeting, which reads as simple established power. Wear a bold shoe for the podcast, to broadcast leadership. Wear a feminine shoe for the cocktail. One firm rule: never wear sneakers as a business leader, unless you have deliberately made them your brand signature.

A laid-back appearance subconsciously says your operations, your timelines, and the way you handle clients are laid-back too, even when none of that is true. That is the message sneakers send.

How do you match your makeup to your outfit?

Your makeup is read together with your outfit, so the two have to balance. If the outfit is bold, the makeup should not be, or the look turns performative and costumey. If the outfit is soft, the makeup can be a little more interesting and feminine. If the outfit has some sexy in it, the makeup should not, or you tip into too much sexy for how you want to be perceived. The mistake is to run a powerful makeup on top of an already loud outfit, a red shoe, a power blazer, an intense face, which becomes too much at once.

The fix I usually recommend is to keep the makeup neutral and adjust the outfit's boldness to the room, rather than the other way around. One variable changes, the other stays steady.

Why should your lingerie be invisible?

Your underwear should disappear, in both shape and colour, because it shapes your whole silhouette. A bra that is too tight bulges at the top and the sides; one that is too big leaves a hollow where the fabric falls. The same goes for underwear that is too tight, which creates a muffin top or a visible mark. All of it reads as a lack of attention to detail, and it can pull a prospect's attention exactly where you do not want it while you are talking big numbers. For business, choose invisible underwear that is flat and does not show or mark, so no lace or design shows through your clothes.

If lingerie is what makes you feel ready for the day, find something in between that you are sure will stay invisible. And under white blouses, always wear nude, never white, which shows through more.

How do you find the right colours for you?

The colours closest to your face change how you look in a way people cannot quite describe but definitely register. The right ones make you look full of vitality even when you are exhausted, which matters especially on Zoom. To find yours, work out two things. First, your undertone: cold or warm. Second, your contrast, the difference between your skin and your hair, eyebrows, and eyes: low or high. Cold and low contrast makes you a summer. Cold and high contrast makes you a winter. Warm and low contrast makes you an autumn. Warm and high contrast makes you a spring.

Once you wear the colours in your season, the difference is immediate, and it shows most clearly on camera, where a flattering colour near the face does a great deal of quiet work.

How do you build a signature look?

People trust what they can predict, and a coherent style repeated over time starts to act as a brand, something established and reliable. Your signature look should convey your essence and your leadership style. The first step is to understand your style archetype, which is linked to the kind of femininity you naturally express, because being a female leader is not about stripping away your femininity to fit a male mould. When you dress inside your archetype you look more powerful and more aligned, because your clothes express how you actually feel and lead.

One client dresses in a classic, timeless style, but pushed too far it became boring and erased her personality. When she leaned into her archetype, her love of historical fashion, she became someone you wanted to know more about. The same woman in different outfits conveys completely different levels of leadership.
