to think you can tell when someone is 'very' wealthy

[nothingbutsnow]

.....more due to how they behave, a sort of self possession than actual money signifiers like clothes, jewellery, etc?

By wealth I mean perhaps more than just well off.

It's something i thought about a few days ago in a garden centre, a family passed by us with teens and there was just something obvious yet not easily described. Clothes were sort of 'anti-mumsnet', like skinny jeans, bright tops, nothing remarkable visually. It made me realise I had observed this before but never thought much of it.
It was more a sort of looming self confidence, not especially pleasant, but noticeably interesting! Not rude or ignorant but disconnected from their surroundings enough to tread on your toes.
I've seen discussions on MN about such things in the past, and the difference in my experience has been they are rarely thin, but more buxom, tall, strident. The teen girl was in skinnies, tshirt and trainers (nothing remarkable) but she had an expression that I can't describe.

There doesn't seem to be an interest in trends at all, especially fashion.

People on here always say it is battered up old Barbour jackets, moth eaten cashmere and dog hair, but I think this is a stereotype rarely seen outside of the rural eccentric.
To me the give away is posture (not so much elegant as assertive), air of disinterest and a certain way of existing in/taking up space differently.

None of this is important, but it's something i noticed. Anyone agree that it is indefinable yet obvious?

People who come from several generations (at least) affluent backgrounds tend to be confident enough in their own skins to be shabby if they wish!

A really super soigné family are likely to be monied but not necessarily 'old' wealthy.

Absolutely. The old trope of a scruffy eccentric farmer type is tied heavily in with the royals only and doesn't translate across the board of wealth. I agree that that the sense of stance and indifference that comes of never having to think nor worry nor anticipate anything in regard to material gain does show. It gives an absolute sense of security that the rest of us are without. Even those that become rich, but didn't grow with it- they never adopt that complete comfort.

Finally some gets the OP

The 2 wealthiest people i know are men. One (owns at least one shopping centre, and has other businesses) dresses in smart jeans and trainers most of the time, speaks very quietly and quite unassuming. The other (i think) is what MN would call old money. He is quite loud and eccentric , wears blazers or linen suits that are usually a bit grubby and crumpled AF , a large brooch, tatty shoes and generally looks like he's been dragged through a hedge backwards.

Prince Charles owns a garden centre. I’m hoping that, come the revolution, he will be working in it.
