Describing clothes as communication is a lot odder than saying that clothes have an in built cost both financial and environmental.
Places like Vinted have allowed people to shrug off the guilt of over consumption. Sure some people will have genuine reasons for putting stuff on Vinted, it doesn't fit or they need the money.
Plenty will just be bored because they've seen that palazzo pant style wide leg jeans are the latest thing rather than skinny. I regularly get deeply vacuous (thank you @GETTINGLIKEMYMOTHER excellent choice of word) articles come up on my Google feed like 'all the cool girls will be wearing these jeans this season' or 'forget black, pairing these jean with this colour boot is what all the cool girls will be wearing'.
Even Vinted has an environmental cost. The energy costs involved in running such a massive platform, the energy involved in shipping second hand goods, the plastic waste that occurs from wrapping those goods to send.
Social media/advertising is incredibly pernicous at getting us to spend money and waste the earth's oh so precious and limited resources. Demonising skinny jeans or trainer socks by labelling them out of fashion is or dated is so irresponsible, it will just lead to waste going to landfill.
I'm not a saint, I'm not immune to advertising however I am making a concerted effort to only buy if I've actually worn something out. I recommend Community Clothing for ethically UK made & sourced timeless pieces that you can wear until they wear out.
So maybe my 20 year old Gap vest that I put on Saturday just gone (that I didn't realise I had a hole in until I was two hours away from home) communicated that I'm poverty stricken, or scruffy. Which just goes to show what rubbish communicators clothes are because if my Gap vest could actually talk it would say, I've done long service, my time is up and I will now be cut up for rags because my owner wants a decent planet for her child..
So perhaps we should worry less about what clothes say, what influencers say, what clothes companies marketing departments say and worry more whether they are good for the pocket and good for the world.
