Hey ! I have been in Hair EXTENSIONS business for a long time, and i have realized that many women don't know their cap sizes.
Cap size is the measurement of the circumferences of a head. Before buying a wig or a hat for your lovely style and
glamor, you need to know your cap size. If not you would always be disappointed at home after you have bought a wig
or a stylish hat. Generally, Hair vendor and supplier often have in stock the medium size of a cap -size.
which 22 to 22.5 inches ( around 56 cm).

But when women with small cape size or large cape size want to buy a wig, she usually has a problem.
And vendor like to push the sale even when it seem not to be looking good.
IN such a case, when we face such issue with a woman, we usually customize the wig for the client in 7 days.
instead of forcing a sale. HEY everyone please buy a cheap measuring tape,follow this pic instruction. KNOW YOURSELF.
