I get them for my boys every year, in Matalan they have childrens Jumpers (hoodies with front pockets) for £2 each and even though they are cheap they are really snug.
Not sure about the girls patterning but for boys they have
Navy Blue zip through fleece £2.50
Army Print hoodie £2
Grey Robot Print hoodie £2
Plus others.
Just thought i would let you all know.
