Well, I own several tailored suits for work. One of those goes for anything betwenn 1000€ and 2000€. It's not really a single piece though. My shirts mostly cost around 200€ as well. I also spent more than 100€ on some of my ties.
Then my skiing clothes cost quite some money as well. I think i paid 400€ for the jacket and around 200€ for the pants.
When I'm not at work I usually wear cheap shit so I don't feel bad if I ruin something. Also, when wearing suits all day every day at work sitting at home in a jump suit is kind of a relief.
