No not a lot wider, well not on Dec anyway and he is a skinny wee thing lol. I have just checked a few things we bought while on holidays last year and apart from being a tiny bit wider they are pretty much the same size as a 4 out of next, butttttttt an American football top we got in a 4T is absolutely tiny, so I am guessing there can be a difference with some things. In saying that it is only that one top out of 7 that had any real difference
2T is about a size 2. Although I always find that American sizes are much smaller than NZ/UK sizes for kiddies, not sure why Like, we have a lovely footed PJ suit for Lachlan that is a US brand and 2T and it fitted him great at 18 months but now at 24 months it's not tall enough for him And he's not overly tall for his age either - sleepsuits here would maybe even be slightly roomy on him.
