Much better, though, are those high end clothes rental sites. Or we could stop fetishising people who have many, many clothes
^^ This. Instead of people thinking you have to have a different and new outfit every time you go out, shaming people who are seen in the same clothes more than once or calling it 'recycling' we need to go back the other way, and make it the norm that clothes are long term purchases as in you wear them for years until they wear out and if you do want something for a big even like a wedding, either rent it, or buy something that will do for multiple occasions and make a point of wearing it to every wedding, Christmas do, big birthday party, function etc for the next few year. What needs to be shameful and commented on is people who always have something new on.
I bought a dress that was expensive to me from Monsoon (was actually 'only' about £80 but this was about 10 years ago) when SIL wanted a 'dress up fancy' 30th birthday party.
I resented the expense but went along with it but then also wore that dress for at least 3 weddings, a couple of Christmas dos, about half a dozen formal dinners for my professional associations and best of all, SILs 40th birthday party.
I did get a couple of comments along the way, but I just shrugged them off or if it was a man who said it, I just asked them how many times they'd worn the suit they had on, which soon shut them up.
