^Very high-level roles are about socialising to win business or to influence decision-makers. In these interactions people strike up "friendly" lifestyle discussions about cars, where you holiday and where you shop etc. to test you out.
They will notice every detail about what you wear and how comfortable you are in that attire. You will start getting cut out of meetings and social circles if the whole packaging of you does not add up or looks like you're trying to fit-in on the cheap. It's a big red flag and folks will avoid you.
Clients judge the value of your contribution on how highly you value yourself. If it looks like you are not investing very much in your appearance and are cutting corners, then you're not going to get very far.
Which is fine of course - if you're happy to stay at the bottom and run around doing admin tasks for those at the top^
This may be the case in some “high level roles” but absolutely not in any of mine.’I have never run around doing admin tasks for anyone. Yes I have to socialise to get business of course, but I do so on the basis of who I actually am (cheap car, no skiing trips) and have no problems whatsoever getting work. Maybe it would have been different a few decades ago but then I also would never had had my role as a woman a few decades ago anyway.
I’m not fussed that you don’t accept my, or any of the other posters’ experiences as valid, but I do care that someone will read this and think that their background/interests/spending will prevent success and either quit before they even start, or get themselves into massive debt unnecessarily.
