My daughter used this for a choir competition when she was in the 3rd grade of elementary school (standard size). It comes with a removable ribbon and can be used for everyday wear, as well as for formal occasions. The buttons are snap-type for easy opening and closing. It has only been used a few times and there are no noticeable stains, but it has been about 7 years since it was purchased. It has been home-cleaned and stored at home. I am offering it for sale, hoping that someone who understands that it is a used item will use it. Length: 47cm Shoulder width: 29cm *Measurements are approximate.
