Do i get enough pocket money a week from my mum?

Hello, I'm 14, and im a boy, I like going to town, or I try hard to, and go shopping. I adore the latest collections from topman, river island, etc, but I only get about 20-30 pounds off my mum to go shopping. And I dont spend all of it just to save up for my next shopping trip in a few days, or a week (though i get depressed if I don't go shopping for about five days...actually, one day is already enough to get me fidgety and look up the newest releases for clothes this season). Do you think I get enough money to buy clothes and accessories?? I dont think so, I want to get limited editions and the latest!! 20-30 pounds is definitely not enough for a satisfying shopping trip unless there is a sale, but sale clothes are usually a bit "out", I want the latest releases!! I need AT LEAST 100 pound pocket money!! Well, I dont get to buy some stuff that I really want anyway, because they're either "feminine" or "pointless". How do the girls get to buy so many lovely clothes??
