Why can I not find a jumper or cardigan?

Honestly... I've been to all the shops under the sun and not one of the fuckers is selling maternity jumpers, cardigans and/or jackets. Ok, not intirely true, Mothercare are selling a gray "I want to kill myself because I'm so dull" hoodie, but it's not really my style.

I've even looked online and although I found one or two shops that sell them, they are of course designer and thus out of my price range.
