You just absolutely blew my mind!!
I grew up in a shabby, acquired-over-time and everything-DIY-house, my grandparents lived like that, our family farm looked like that, when I moved out our house looked like that… when I first moved out I took my grandparents’ stuff with me - in the 10 years between their death and my moving out it had been stored in an old barn, and it smelled a bit like cow for a couple of years. Storing furniture was only natural as everyone assumed the grandkids would eventually want it. As you may have guessed, no one in my family was wealthy (and that’s an understatement). I didn’t stay in the rural, conservative community I grew up in, but some of my friends did, and I always wondered why they had such cookie-cutter homes. I chalked up their “sets” of furniture, dinnerware etc to the difference between rural/urban and conservative/progressive trends.
But you’re right, it’s about not appearing poor, like my family, it’s about feeling wealthy because you have everything and it looks nice and matching. I remember when my highschool friend got married not too long after school (her husband was still in college) and we played a game where we’d name an exotic kitchen tool and she would say if she had it. We couldn’t come up with anything she didn’t have, and she was so proud! She was especially proud that everything was paid for, because a lot of people we knew back then would get their furniture sets on payment plans - another reason to buy a set. As teenage girls, we all slowly collected our trousseau underneath our beds.
A lot of people I know in the city have non-matching interiors, but you’re right, while in our case that has to do with being from a low-income background, a lot of people we know here are from pretty wealthy backgrounds. I haven’t checked where their furniture comes from, I’d just assumed it was cobbled together like ours, because you can’t find anything like that in the stores, but it could very well come from some designer vintage store where everything is €€€. Apparantly we still don’t go to the shops where the real privileged people go, since all we see is boring, matching Pinterest style.
We got rid of all low-quality hand-me-downs/thrift store things, so for example we let go of the third hand, worn out Ikea sofa, but we’ve kept everything handmade or solid wood. I’m sure our house will always look a bit mismatched, whether appealing or not is in the eye of the beholder.
Speaking of trousseaus, traditionally in the Netherlands they would be collected in a wardrobe with doors. Upon marriage, that cupboard would be used as a wardrobe / linen closet in the marital home. They were called maiden’s cupboards and a antique one has been very high on my wishlist for our new house, but they are very expensive these days. I still hope to find one in a thrift store one day. They seem very practical for craft supplies!
