This has an adjustable band, with a sharp metal hook to secure it to the metal eye on the other strap . The bow itself is child sized, but the band could accommodate an adult with a smaller neck. I adjusted the neckband all the way smaller and it just fit my 8 year old son. Taking off one star because the metal hook really is sharp and cheap and a child using this could conceivably hurt themselves while trying to take it off. It may be obvious that a parent should help with this tie, but for kids who may be using this tie (ie middle school aged children at a strings concert, the age where kids want to do things themselves) it's something to consider. A plastic buckle or plastic hook might have worked better on this.
