Dear Customer, hello � � For the most comfortable use, measure your head circumference with a tape measure just above your eyebrows, slightly above the middle of your ears, from the widest point at the back of your head. Take the measurement without putting too much pressure on your head. If you're planning to use it with a bonnet or headscarf, it's recommended to take your measurements accordingly. Our collection offers multiple size options to accommodate different head shapes. Choosing the size closest to your measurements ensures the perfect fit and optimal comfort for the hat. Thank you from the bottom of my heart for choosing Mağazam Online and Lions Online. With love and care, Your Online Store Customer Relations
