I went even further when dd was younger and she does so now having learned from me - "frankensteining" old clothes to create new ones:
Shorts and skirts made out of old jeans and trousers that became too short (dd is very slim and tall so often things would still fit on the waist but not leg length)
Taking sleeves off one top and adding them to another especially where the other parts of the garments had become stained or worn
Making scarves, hats, mittens, tie style belts and hair accessories out of the "rags"
Dds first year of life we were very lucky to have been given several bin bags worth of used baby clothes by friends who'd completed their families, admittedly gifts from family too, the only items clothes wise we had to buy till she was about 18 months old was a few vests and tights!
I've bought loads over the years second hand mainly from charity shops, it's nice to not only be doing better for the environment but also helping charities.
I have ocd so everything washed before wearing but then it's fine.
Only thing I won't buy second hand if well worn (obvious from the soles if not the rest of the shoe) is shoes as both dd and I have dodgy feet anyway in different ways and we don't need that made worse, shoes "mould" to the wearer which can then cause issues if worn a lot before being handed down and the next wearer can then experience difficulties, especially things like heels.
I'm also very good at looking after clothes so they last me ages (same not true of dd I'm afraid even now she's an adult), I wash and dry carefully, remove stains immediately (and I'm pretty good at this if I say so myself) and repair minor issues immediately too (small holes, loose hems and seams) some of my repairs are...inventive! But whatever works
My parents have your attitude but it's borne from having been very poor themselves growing up and wearing unsuitable and embarrassing hand me downs eg my dad vividly remembers having to wear a bright yellow girls blouse once that was his older cousins and getting bullied for it (he's mid 70's in the 50's this was not as accepted as it may be now, especially in working class glasgow!), my mum remembers having to wear second hand school shoes that hurt and damaged her feet.
They struggled with the knowledge of my siblings and I doing this at first (my siblings don't do it quite as much as I do either but they're quite conservative style wise which is a factor) my sister sells a fair bit on eBay etc she's a good salesperson.
@Time40 that's an excellent suggestion to ease the op in
Also op it's not just on eBay you get bnwt also freecycle and Facebook market pages do things this way, I'm always seeing stuff advertised on Facebook this way, I tend not to buy them myself simply as these tend to be newer fashions which isn't my "thing" but dd does it loads!
The age you're talking about too, tbh they get SO messy it's not worth wasting new clothes on. I would recommend you invest also in the following though:
Large container of salt
White vinegar
Baking soda
Bottle of lemon juice
Original green fairy liquid (not any of the posh scented ones!)
Nail polish remover
A lint remover (makes removing glitter and similar SO much easier!)
Always tackle stains BEFORE washing the item, ditto repairs.
@LongTimeMammaBear I'm old enough to remember clothes rentals for all kinds of things! My dad was army and when he reached the point he and mum were attending balls, it was ridiculous to spend a lot of money on a dress mum would only wear once so there were often rental set ups on base or in a shop near the base precisely for this reason, they could also rent matching bags, head dresses, jewellery etc when I married the bridesmaid dresses were rented nobody does that any more either which is also ridiculous as they're not the kind of thing you're likely to wear again and very expensive. Mum had one pair of gold heels and one pair silver that she'd wear depending on colour tone of that ball's dress. She has some amazing photos from that time as renting also allowed her to take risks style wise that she might not have attempted if she was buying.
I haven’t thrown away any of his clothes. They’re all vacuum packed in storage bags.
Unless you're hanging onto them for another child, get them sold and make yourself some money.
Yay! Well done for bidding!
