I prepared this for a trip back to my hometown in the snow country, but my child refused to wear it at all... It's only been tried on. Perfect for the upcoming cold season! It's made of very soft, fluffy fabric. I think it's a size for babies of the "wan-wan" generation (toddlers). This soft polyester sleeper is the perfect size for a baby. - Material: 100% Polyester - Size: 35 x 50cm Thank you for looking.
