I wfh and never have to look dressed up. I have a technical waterproof for (rare) hikes, a long black coat, a proper Scandinavian winter coat, a trench type thing, a mid weight puffer and in the sales I've just convinced myself I needed to get three more ( 2 mid season, one fairly warm). I don't 'need' them, they will add variety to my wardrobe but clearly are not necessary. But I love coats!! I'm sure I'd have more if I hadn't put on weight 3 years ago and had to get rid of most of mine and start again. It's becoming a bit embarrassing to explain to my OH what the newest package is, and I should probably save my money for other things.
Am I going overboard? How many coats do you have?
