Wow, I'm so bad when it comes to sizing, but as soon as I get my daughter started on her lessons I'll try to measure around it & let tou know. I apologize for the wait, but wanted to reply so you didn't feel I was ignoring your comment. Have a blessed day!
Ok so not sure how else to measure so I measured around the bottom & it measures like 37 inches & it is elastic so room to stretch some if needed. I hope this helps.
