Help me with this situation?

Okay so I'm a 14 year old who makes money via instagram and all the money goes to my brother s account. For the past month I have been saving up for an iPhone 6s plus 32gb. Its £400, and my bro is saying I shouldn't buy it and its a waste and i shouldn't buy it and that he won't let me. I'm about to buy it right now, do you think I should? I worked really hard for this and he said I should get the iPhone 6 or 6s since its cheaper but they are too small for me. What do you all think about this situation cuz I'm feeling very overwhelmed about this whole thing. Tbh I just want my phone. I don't know tho. I know this situation isn't that deep but please gimme answers xx

You can buy what you want Iphone 6s is not a bad phone if you need one. Order your bro to give you the money for shopping.

Go ahead and buy it. It's your money.

Since the money is as much his or more so than yours he might be covering for already having spent your money. In his account he can do as he pleases.

If you have managed until now without this phone obviously you don't really need it
your brother is simply trying to help you with your finances and you obviously are under age and need some financial management instruction
true you worked hard for the money but there could be something far more important than this to use it
