Fit Notes
Our sleepwear is designed with comfort as the priority. The fabric is naturally soft and breathable, allowing ease of movement during sleep while remaining gentle on sensitive skin. A relaxed fit is recommended for nighttime comfort. If your child is between sizes or prefers additional room, selecting the next size up may provide a better fit.
