I've been selling my old clothes for many years, and I buy the occasional thing from business sellers, but it's very rare for me to actually buy clothes from private sellers, even though I am one.
I bought a high quality jacket, advertised as only worn once. But the stink, I mean I almost thought I was going to throw up. I could smell it as soon as I started to open the parcel. It's a dry-clean only jacket and would cost about as much to dry-clean as the item cost me in the first place, and even then I've gone off the idea of wearing it now.
Given that nothing was mentioned either way in the listings, AIBU to expect things not to be drenched in perfume? When I list things myself, I never say "it doesn't smell of perfume" because I would take that as a basic standard. I only mention smells when there is one, e.g. if something's been in storage.
Also, is there any point at all in messaging the seller to say I'm a bit disappointed? She's been selling for years and has lots of feedback, so I don't really know if it would achieve anything and presumably she'd disagree anyway.
