This is a beautiful peach colored newborn baby girls tutu with matching headband and top cover. This outfit will make your baby look adorable in her first baby pictures. The waist line is 13" around without stretching. It does have plenty of stretch at the waist so I can not give a true size. You will have to measure your baby's tummy and use your own judgement. Depending on your baby's size it could fit anywhere between a newborn to 6 month baby.
