I've never heard of Michael Kors bags but that doesn't shock me. Personally I shop very exclusively. Exclusively from charity shops because I'm skint. I don't see that as a moral failing on my part. I blame that on the chronic illness which stopped me working 20 years before I ought to have retired tbh. I don't see why what anyone earns defines them for good or ill. I think their values & the way they live their lives does that.
For instance, I judge Sarah not for spending £80 on a bag. I judge her because I know for a fact we'll never see her pay 80 quid to get one of those kids a decent pair of shoes. It's fake Crocs & faux Uggs for them. They'll wear them till they're two sizes too small as well & bugger how cheap, ill-fitting shoes can deform a child's feet, corrupt their gait, damage their knees & hips & lead to chronic back problems.
The term "All brass & no class" fits her perfectly.
