It's delighted to learn you approve of our hair! the wig cap is average size(22.5 inches), which is suitable for customers with a head circumference of 22 inches to 23 inches. As shown in the first image, adjustable straps replace the adjustments at the back of normal wigs, enabling a snug and comfortable fit, and adjustable cap sizes to ensure a secure fit for different head sizes. We look forward to working with you again in the future!
