My baby is a chunky 6 month old and I purchased the 6 month old size short sleeve onesie which fit great. The fit wasn’t too tight or too loose. I didn’t want to get a bigger size because she was taking pictures and I wanted it to be a comfortable fit. The onesie was nice and soft and the glitter lettering on the onesie was so bright, vibrant, and it wasn’t the cheap kind where glitter is everywhere. I loved the tutu skirt because it was well sewn and it’s adjustable plus the pink color was such a beautiful soft pastel just like the picture pink. The color is so pretty and the bow sealed the deal as it looked so nice with the entire outfit. Oh and the seller included a free bow as well which was nice. Overall I highly recommend this outfit and would purchase again from this store.
