When you go on dates, does he pay, or do you go Dutch? Do you get the vibe that he's very conscientious about money, or he doesn't make enough, therefore he might frown upon your hobby?
I'd try to get to know the guy first. Then slowly introduce your Chanels, there's no need to have a lengthy convo about luxury shopping, most guys won't even understand what the hell you're carrying/ talking about.
Funny story to share: 10 years ago, I went on a first date with this guy and carried a 30 Birkin. Guy had absolutely no clue the whole day, it wasn't until dinnertime we were at a restaurant, the waiter (who was obviously gay and super into fashion) screamed that it's an Hermes birkin, 10,000 dollars, gesturing wild like he just won the lottery, and wanted to take a picture. Then my guy choked on his drink. Hahaha.
