There could be several factors involved.  In some societies, women are the keepers of tradition.  When holidays arrive, they make the preparations.  Often, they stay at home and tend to the children and the aged.  Thus, they receive less exposure to new ways.  When girls become women, they are married off to other families and continue the tradition, but when boys become men, they go out into the world and learn new ways.  In addition, men may worry less about the effect of change on social patterns if woman seem visibly traditional.
