I did a double-take at the 3.5k Euro spend per year on clothing. My own spending is probably 2-3 orders of magnitude smaller. But then I saw how many shoes they own, and the fact that they have a summer house where at least one pair resides. This person lives differently to me.
Not that OP is actually doing this. They're spending a lot of money because they're buying a lot of mass produced crap. The 'luxury' of those low cost-per-wear Converse is a flat insole that will put a podiatrist's children through school and a glued outsole that fails early and predictably. And then they have 5 other white sneakers doing the same job in their wardrobe. They could have spent less overall and got even better CPW from resolable, calf leather white sneakers.
