DD is going into Yr 1 and is progressing from polo shirts to a proper cotton collared shirt. He is inheriting his DSis's shirts but he is saying the collar is too tight. They do look quite tight but no digging in.
Are girls shirt collars narrower than boys shirt collars (we're talking aged 5 shirts here). He is quite skinny so surprised that this would be a problem.
Any thoughts gratefully received.
