I've known for a very long time that I have way too many clothes, and since leaving my "corporate" jobs, I no longer wear the same kinds of outfits as I did.
I do agree that if some things "give me joy" (ie I love wearing them, love the colour or they have sentimental attachments) then I will keep them, but going forwards I do know that I don't attend corporate hospitality nights at the ballet or business dinners any more, so I don't need those kinds of outfits.
For our photo shoot, I picked out a couple of things to keep and a couple of things which I knew I would get rid of - but actually it did not work out the way I thought it would.
It wasn't expensive - in fact it was one of those impulse buys online from a company I had never heard of, so wasn't expecting it to be very good quality.
