In reply to DreadyCraig:
Once tried on a size small Moon Tshirt - one of the bamboo based fabric ones.
Small.
It was massive.
Their tshirt labels show that they go down to XS but I've never been able to find any XS sized ones.
It's daft because I fit S or M in all other Tshirts I've ever tried.
I suspect the different types of Tshirts (bamboo / cotton / etc) have very different sizing - where the two tshirts different types?
Si
PS If anyone from Moon clothign or their distributor is reading this and wants to sell me an XS "Bus Top" T-shirt, then go for it!
