Oh honey, I indulge in sinful desires ALL THE TIME.I just bought my first LV bag and I am so excited! I ended up on this thread because I saw the "How do you react when people ask how much your bag cost" comment. I am so worried that will happen to me! I have wanted a classic bag that will go with EVERYTHING for so long...especially since whenever I switch purses I end up leaving something important (ie wallet or lipstick) at home! So now I am hoping my new LV Monogram Sully will solve that problem and add a touch of class to my wardrobe. But I can't help but be nervous....none of my personal friends carry LV. I am afraid they won't understand. I feel like they will think I have misplaced priorities for spending $1200 on a bag. Maybe I feel that way because I truly believe that is true. Am I, by buying the bag, indulging some sinful desire? I haven't given $1200 to charity this year. Ughh. I feel guilty.
Sometimes I even buy a new purse.

As long as you are happy with your purchase and have no regrets, you have nothing to feel guilty about.
I don't mind telling people what I paid for something - I had a few friends ask me what I paid for my car when I first bought it. I just kinda thought, look it up on the internet if you want to know.
I think there are a few people around that may recognize LV or Balenciaga or whatever, but sometimes a lot of people assume they cost a lot more than they actually are.
Own it, be proud of the fact that you bought it yourself and don't worry so much about whether your friends think you're being frivolous. I have a few friends that are not, um, as "financially stable" as others so I tend not to flaunt any designer goods around them - not that I flaunt my purchases, but you know what I mean. I just dont carry certain bags around them because for some of them, even a $285 Coach bag is quite a luxury. I don't feel guilty, but some of them may not be able to afford $1500 purses, so I don't go out of my way to make my friends feel like their Fossil or whatever purse is somehow worth less than mine. I happen to be single, while some of my friends are single moms or in a more difficult financial predicament.
I think there's been this thing with us women for a long time to almost brag about what a good deal we got on something. "Oh, these Tod's loafers? I got them at the Factory Outlet for $79! Can you believe it?" Or brag about our dress from Target while we wear our Louboutins with it. Like we have to justify something. It's weird.
