L'oved Baby newborn/preemie size is intended for 1.8 to 3.2 kilogram babies, and fits quite accurately. The zero to three months size is intended for 3.2 - 4.5kg, and while definitely fit longer and be a little bit roomier than NB sizes, still offers a nice tailored fit in the torso and arms.
That said, all of L'oved Baby's clothing is cut a little long to account for the shrinkage that will occur after first machine wash and dry since our garments are made with organic cotton with no synthetic blends.
If you are looking for a form-fitting coming home outfit or a newborn photos outfit, we recommend the newborn size, with the understanding that you might need to line dry it if you feel that it is going to be too small for your baby once machine washed/dried. Otherwise, if you have other children who were born bigger than 3.2kg, we would recommend going with size zero to three months, as it will last longer than the newborn size. It's really a preference as to what you are hoping to use it for (immediate versus longer-term fit). :-)
