My daughter was 70th percentile for height and weight. I purchased two sizes. One was 0-3 months and the other for 6-9 months. I returned the 3-6 months as the 6-9 was a perfect fit despite her only being three months when 4 months when purchased. I can’t say it was true to size. The suits offer a LOT of stretch so I’d say it’s safe to go up a size in relation to age.The hat is a bit big. My baby is now 7 months and it still doesn’t fit her well. Constantly readjust otherwise it falls over her eyes.
