I am an adult and it fits me tightly.

All rulers, meter sticks, hangars, racks, train-tracks, etc. used to display or give size or color reference, etc. do not go with he item unless specified.  I hope you take a chance, because people like Columbus took a chance.  I live and ship from within 50 miles of Portland, Oregon.  I use USPS for my ease and it enables me to ship at that price to Alaska, Hawaii, Puerto Rico, Guam, APOs, etc. that have US Postal Service.  If you request it then I can go to the FedEx or UPS store.  The store is about 8 miles away and I can only fit my schedule on Tuesday.  Shipping outside the U.S. needs to go USPS Priority or USPS Priority Express because both of those include insurance plus select Delivery Confirmation.  I do combine shipping.
