This dress is a size large. It's supposed to fit a 9.5 Kg baby (21 lbs.) but I'm thinking it ought to be a really bulky 9.5Kg baby. It's huge! Also, I think the neck is too big.
It did work up extremely quickly and the instructions are clear. The pattern was supposed to be for a layered look, such as organza over cotton. But I just chose using one layer of this cute pink and chocolate polka dot cotton fabric.
I made it once before in newborn size, 3Kg (7 lbs.) but I think the baby I made it for couldn't wear it until she was well over 7 Kg. (15 lbs.)
