Beanie is made with 100% Acrylic Yarn and an Ultrasuede tag.
Standard Size fits 21″ to 23″ head circumference.
Large Size fits 24″ to 26″ head circumference.
The mannequin measures 23″ for reference and is wearing a standard size beanie. A 24″ head circumference would just make the beanie more fitted and less Slouchy. A smaller head circumference would make for a more slouchy hat but beware there is such a thing as too slouchy. Beanies do stretch and soften with continued use.
