DS1 wore something like this but from M&S when he went to wedding at about 6 months. What does he typically wear? You could probably get a pair of decent trousers and a clean teeshirt / tank top from most places.
I would like some suggestions please :-) i'm going to a wedding in march and i don't know how to dress ny DS. He'll be 7months then so i want something that will look nice but be practical and comfy for him. If anybody has any links or website suggestions they'd be very much appreciated!
