To use this adorable penguin - shaped baby costume, simply dress your little one in it for a Christmas party or any special occasion. When it comes to sizing, choose the size that matches your baby's height as described. For care, you can machine wash it in warm water on a gentle cycle. If it needs bleaching, only use non - chlorine bleach. After washing, tumble dry it on low heat and take it out right away. If there are any wrinkles, you can use a warm iron. Keep in mind that the color on your screen might be a bit different from the actual costume because of monitor settings.
