My baby is measuring big what should I plan for a going home outfit?

Hey my baby boy is due July 3rd. He is definably a boy because we had multiple scans and he flashed us tons in them. Lol anyways it will be hot (I live in Arkansas) but we don't live far from the hospital and it's mostly for pictures. I want to make sure he isn't to warm or cold. I have a little beanie and a bucket hat. Which would you suggest? He is measuring 2 weeks ahead and at the last scan he was 4 oz over that was at 21 weeks. I have a newborn onesie and a 0-3 month Romper. Should I bring one more size. With the onesie I have some cotton newborn pants and some supper soft socks. Does this sound like it will be covered? Also what free stuff did the hospital give you? I am bottle feeding and was going to bring a bottle and formula but heard they provide it. What about a pacifier? Thanks so much
