I don't really understand 'valuable' wrt clothes
Everything I buy I wear
The most expensive single thing was my suit (£200)
It gets worn maybe 4 times a year
The cheapest were my socks, which get worn every day
Which of those is most 'valuable'

Long term investment pieces.

Good quality shoes, coats, jackets, and bags. High-quality basics like my oversized Brooks Brothers button-up from the thrift store. Truly stood the test of time. Most of the other stuff is fast fashion and currently falling apart if it hasn't already.

Great dresses for different occasions

I learned in the past few years to actually buy what I need.

Probably lingerie, I love it.

i buy warm clothing on the top and cold/warm clothing on the bottom.

Leather boots. Wool coats, cotton shirts, scarves.

Shoes, trousers, pullovers.

No.

Natural fiber shirts.-- can't beat a silk top for 5 dollars at goodwill. I wore it to weddings, so it was a win.

my blundstone boots. worn every day working in landscaping, and also my most professional office shoes.

When I didn't 'settle' for an item, but was happy with it from the start. Something that was simple and classic but not too 'basic', so that it felt special to wear.

I can't remember most of my purchases during that time frame.

My wedding dress.

Coats, they last and cost more

A couples of my bags and shoes

Really high-quality shoes never disappoint. Go to the designer outlet mall and try on expensive shoes to find a pair that really fits.
Moto jackets.
