Where to purchase uniform for the large of head?

[bluechameleon]

My 4 year old has a larger than average head and we have struggled this year with his logo sweatshirts. He outgrew the neck holes when the body and arms were still slightly too big. Does anyone know of any supermarket/department store sweatshirts that are more generous in the neck area? We need bottle green if that makes a difference. Thanks

Could you get him v neck jumpers? Would be easier to get over his head than sweaters.
