I think it’s definitely dependant on how much you use the suit, but if the suit makes you happy and if you use it regularly then I don’t think they’re a waste of money. That said, they are 100% a luxury item so it’s really important to make sure your living essentials are covered before you invest in one.
Also prices do vary a lot between makers. My suit is a full suit and I got it for $1500USD. It depends on the experience and popularity of the maker, as well as whether the maker is making a career out of it or doing it for fun.
