I am slightly bemused by my MILs reaction to a birthday present we bought DN at the weekend. It was bit like this:
Top
i.e. long sleeves layered under a t'shirt, white sleeves, dark colour tee (not as boring as that, it was from his fave footie team)
MIL declared SIL should cut the sleeves off because it will run. We might as well have bought him just a t'shirt!
Anyway, I have plenty of tops with both light and dark colours in and they don't run into each other. Shops colour fast test clothes nowadays don't they? Why else would they sell clothes like that?!!!
