Review: READ FOR SIZING - We loved this for our son’s first birthday. He looked adorable in it. I will say the bum and waistband was a bit snug and straps were a tad long. Size was just off on my baby boy but he enjoyed having it on and it didn’t bug him. great quality! We ordered 12-18 months yet he is currently wearing 2T lol !
Review: Even cuter in person! - I absolutely loved this outfit for the little one’s first birthday. The fabric was a pleasant surprise—it feels soft, comfortable, and looks really nice. The size fit perfectly on a one-year-old, and the design looks absolutely adorable when worn. It’s one of those outfits that makes a birthday look extra special while still being comfortable for the baby. I’m very happy with this purchase and would definitely recommend it.
