I mean, if she (I'm assuming the 20 yro is a she) has the money to buy an Hermes-anything, I don't think there's an issue? They're very nice and durable bags. If she's not as wealthy and could be putting that money towards other stuff, it's probably not a great financial investment, but who am I to judge?
Would I do it? I'm gonna have to say no. But if she's not broke, has been saving up for it, and it makes her happy? More power to her for managing her finances that well.
I'm too lazy to Google what that is but from the comments I'm gathering it's an expensive handbag.
I think everyone has their thing they spend money on. No one here has a right to say thats ridiculous if they own any luxury item like a big screen TV with surround sound or a Playstation or a sports car etc personally I would never spend a lot of money on a handbag, but I've dropped lots of money on vacations for 5 star hotels and eating out at nice restaurants.
