I would park clothes in a separate category.
Or at least get some new stuff you do like before getting rid of the other stuff.
As for the rest of the house, ours still very much a work in progress, but it's great.
Work out what you need for what you want to do. Say you want to make clothes, keep sewing machine and all things needed but perhaps get rid of the crochet and knitting needles (you can pick these up 10 a penny in charity shops).
I now, almost always, get rid of books I have read, too much to read, new stuff all the time, only so many hours in the day.
Chargers for phones long gone.
Etc etc
You can find things easier, you do more of what you want because you have the space.
I had to throw out (donated) half our pans when we got an induction hob, keep saying I will replace my favourite two, but I haven't needed to.
Life is so much easier.
You won't regret it. Just don't do it too quick.
Some stuff is easier, redundant chargers, other stuff but more difficult.
