Should I spend my money on clothes or save it?

I'm saving money (just for whatever) and I want to get some clothes from the site BlackMilk,
there's 4 pieces of clothes I want that together would cost about 360 (before shipping) I know that sounds like a lot but I have always wanted BlackMilk clothing (And please don't down it saying expensive clothing is a rip off, etc because BlackMilk is top of the line its quality is great you can't match it, and some of the designs they have made only) I'm only 13 and I don't have this money atm but I plan to save (for a while lol) but I also have really nothing else I could need, I have everything I want (Just got a new laptop, bike, flat screen TV for my room, getting a Xbox 1, and I'm upgrading to a Iphone 5 not trying to sound greedy or anything but I have everything I want/need but I think it would be rude to ask my mom to buy me these clothing and I know she wouldn't, she doesn't trust online stores) but my friend said it was stupid (I should her the clothing I wanted and I really think she had more of an issue with my style/choice of clothing more than the price of it) I don't know, what do you think?

I think if you like it get it

Do both put say 70% away in a saving & the other 30% on hat you want! Do that early in life and you will be far ahead of everyone else…

Through the efforts to get what you want, there's nothing wrong with it, support you.

If you develop the habit of savings at this age, you will not have any problem in future.

If your family's rich, then yes. If not, grow up girl.

Buy any clothes you need, but save the rest of the money.
