Ash - the advertised size was 00 - thats why I got it cos we got DS named when he was nearly 6 months and I thought it was going to be a good fit. However, I think (based on his other clothes) it would do as a 000. I will take pics and email them to you if you want? I can do that tonight, I don't know how to upload them into the gallery (hence why I have no pics in there!!!) It comes with a little bonnet as well (which could be a little girlie, but came with the outfit!!) oh, and little shoes...
