I don’t buy clothing as “investments” and I don’t think of them as being valuable or not. I am only happy if after I get rid of it, or want to sell it, that it sells for more than it was worth.
Honestly it’s a crapshoot in terms of money for clothing being valuable or not.
You never know what people will value.
I personally buy what I like, vintage or not, and then just wear it until it no longer serves me.
I suppose if you had a Louis Vuitton original steamer trunk that would be worth a lot… *shrug* Or some sold-out piece that everyone is after, but I don’t follow such clothing trends.
I only know about them from reading books, like that the Chanel Boy Bag is very much lusted after, or that Chopard (you know the fine jeweller that has clover leaves as their symbol?) have had their jewellery go up in value over time if you “invested” in their pieces. *shrug*
