I am pretty sure that almost every person in my life thinks it's tacky and amounts to conspicuous consumption.
I don't let it deter me from carrying and enjoying my bags, though. I recognize that studying/appreciating the history of craftsmanship and design and fashion is a fairly niche interest and I don't expect the people in my life - even those with substantial net worth - to get it. Even more than that, I'm actually GLAD that I'm not surrounded by people who place a lot of importance on designer labels and material things. I'd rather be judged as kinda silly for spending too much on my bag than for NOT HAVING the "right" bags or cars, clothes, homes, vacations, etc. That would be a much more exhausting type of crowd to hang with, for me (and frankly, it probably would turn me right off luxury goods).
I just try to wear my bags with style and confidence and not make a big deal about fussing over them, showing them off, or, on the other side of the coin, hiding them. It's just my purse. It's not anything for anyone else in my life to worry about. On the few occasions a family member has remarked on a new bag, I've just responded, "oh yes! - I love it so much" and then let the topic drop. It would be easy to slide into shame or defensiveness and feeling like I need to justify it - but that really just makes the whole dynamic so much more awkward. I'd rather just project gratitude, grace, and class about the whole thing and let THEM feel like the tacky one for obsessing about the cost of someone else's purse.
I hope that you're able to find that balance between enjoying the things you love and feeling comfortable around your friends and family! Once it goes on long enough, they'll get used to it and stop reacting - they'll just think of you as the lady with the fancy bag, and that will be your "thing."
