What is the difference between Full Lace Cap with Stretch and Full Lace Cap without Stretch?

These two caps are with lace all around the perimeter and available that you wear your hair in updos and high ponytails. When the caps are glued down, the wig will have a natural hairline all around the perimeter. The unit can be parted anywhere as you wish.
Full lace cap with stretch is with stretch in crown and this will be helpful for adjustment on your head size. Full lace cap without stretch does not have stretch and can be worn by women without hair or with scarce hair.
