I hope what I'm about to say will be taken in the spirit it is intended and not in a negative way, but I also feel you are too young for such a pricey bag. I'm 51 years old and feel very strongly that we all should have to earn our way up the ladder of the finer things in life. Sure, you are planning to pay for the bag yourself and that's fine, but to own a
Gucci bag as a teenager is just not appropriate. I appreciate that you have an eye for the good things in life at your age, but I still feel strongly that we should earn our way to such status items by living life, learning lessons and mostly, having the disposable income to easily purchase things like this.
Think of ALL the more age appropriate bags, clothes and shoes you could purchase with what this one bag (really intended for an older woman) will cost you. I'm a pragmatist. At your age I'd rather have lots of cool things versus one sole handbag. If you were my daughter (who is 20, by the by), I'd be telling her the exact thing.
My two cents.
