Thank you for viewing. Regarding the size notation, it is strictly: Age: 9-12 months Height (cm): 68-74 Weight (kg): 8.3-10 Chest (cm): 46-47 Waist (cm): 47-48 Hip (cm): 47-48 The above are guidelines. It is a knit material made of a cotton and polyester blend. (60% cotton, 40% polyester) Machine washable. It has a soft and gentle feel on your child's delicate skin. It has a crew neck without tags, so I think it will be comfortable to wear. It's a full-zip design, so it's easy to put on and take off, and also easy to layer over a bodysuit. The long sleeves have fold-over mittens at the cuffs, and the bottom part is designed to wrap around the feet, keeping them warm. The color is only this one color.
