IMPORTANT: Make sure that you measure ACCURATELY. If you do not measure properly, your wig may not fit. Measure at least 2-3 times to be sure. Use a soft measure tape to measure. We take measurements in whole and half inches. So please round your measurements up not down. Example: 12 3/4 should be rounded up to 13 and 12 1/4 should be rounded up to 12 1/2.
