Although this may fit an average weight new born (7.5lbs) it is better suited to a baby with a lower than average birth weight to get a good amount of wear from it. See the wee rompers to match (MB177).
Measures 36cm around the chest and 19cm from centre back neck to lower edge. The button holes for the under side become part of the all over pattern.
Knitted in Shepherd Babywool Merino 4ply (fine).
