Halocho #556 - Cross-dressing

A man may not wear clothes or jewelry that only women wear - nor may a woman wear men-only apparel.

"Who-wears-what" is defined by local custom and may change over time.

A man may not pluck out even a single white hair (unless all his hair has turned white) nor may he dye his white hair. A woman may.
