@SarBear1980 have you found eBay a good place for selling clothes? I've been using Facebook without much luck, great for other things just not clothes, although I have sold a few.
@TableNiner I've not done so well really. Spent less than I usually would to start with, then had a mass spend this month. Suppose some of it was necessary, replacing tights that have worn out and have holes in.
I started shaking things up this past year. Usually I feel a bit guilty for buying things, continuing to wear the old things whilst my new stuff sits around until it doesn't feel new any more, then gradually including them into outfits made with my old stuff. This time I decided to wear exclusively the new stuff. For almost 3 months I've worn a different outfit every day made from the new stuff. It felt like a game and has been a distraction from lockdown boredom. Now I'm missing my old stuff and looking forward to wearing it again. I've also thrown out some tatty stuff and anything where the fastenings have broken. I've found I don't feel bad about it or miss those things.
The things I've bought this week are better, more expensive and more carefully chosen than usual. It's strange because I've spent so much on so little. £345 on 3 dresses (1sleeveless, 1 short sleeve, 1 long sleeve), a hoodie and shorts lounge wear set, a t-shirt, a long sleeve top and a jumper. I don't feel bad or wasteful because I totally love each piece, everything is completely different to what I already have and I feel better that I'm bringing less into an already pretty full up home. I made a conscious effort not to buy anything similar to what I already had.
I'm considering another experiment for March. To set aside everything except the stuff I've failed to sell and wear that. It means I'll have to get creative with alterations to make things fit, and make do with some things that no longer feel like the clothes my current lockdown self wants to wear. But I must have loved something about all these things at the time of purchase, maybe it'll help me change my mindset about shopping to rediscover that. If nothing else it'll tell me which brands survive being washed over and over and which don't last. That's not something you notice when you have a lot of clothes and can't keep track of how often you've worn something.
I'm going to try really hard not to buy a single thing except food during March, I can imagine doing this, it feels achievable.
