Product is super cute! I ordered a newborn size and the size that came is a closest match to her 12 month clothes. Going to make it work but my advice is to size wayyy down!Cute. Liked the saying and It was soft too. But it was super see through and the buttons were too far apart so the tension each one had they kept coming undone. For it being for one day it was fine and did it’s job but if he had to wear it more often the buttons wouldn’t last. for sizing definitely Go by weight not by age.The outfit is good quality. The decal is not the cheap iron on kind. The only issue I have with it is the sleeves are unusually long. The rest fit true to size.Shipped and delivered very quickly. I ordered the 6-9 month and it fit my 6 month old perfectly (she was about 16 pounds and 27 inches long when she wore it). The material wasn’t too thin and it survived the first wash. I was very pleased with this purchase.Cute.. Loved it... material great for one day not too thick but definitely the cutest outfit and great for the one day useYou could see my sons diaper through the outfit and the buttons around the legs were tight.Nothing I don't like about this outfit, it's soft, stretching, lightweight. I just love it!Loved this outfit on my son ??
