I used this as our "take home outfit". I purchased the newborn size and it fit her perfectly. 7 lbs, 12 oz. 20 in long. It fits her so well that I know I will only get to use it 1 or maybe 2 more times and she will have outgrown it but that's ok. I wanted it to fit her for going home. I did wash and dry this 1 time before she wore it and the hat seemed to really shrink. It fits her head but only the very top and does not come close to covering her ears. Which means it stayed on her head for a total of 2.5 seconds and fell off.
