Boys' red shirt

[ponygirl]

Does anyone know where I can get a plain red shirt for a 7 year old? Ds1's class are having a Spanish theme for the Christmas concert and apparently this means he needs to wear a red shirt and I can't find one! Help!

what about a red school shirt - bet some school has red shirts?

eBay?

dye an old white one ?

Am looking for a school shirt - good idea, thanks! Don't have an old white one, only a really nice Gap one: Ideally, I'd get a nice red one then he could wear it at Christmas. Have looked on ebay too, but they all have logos and pictures on them.

Mothercare had beautiful red corduroy shirts last time I was in. Not sure what size their clothes go up to?
