In this our hot Naija weather,we surrender ourselves to clothing we can't do without; tank tops, tights, leggings, beach wears, handless gowns, etc all body revealing clothes.And with these comes the exposure of our arms,under-arms and legs.
There's really no hygienic purpose for body shaving (except of course the pubic hair).There just seemed to be a growing tendency in the generation under 20/30 to see body hair as disgusting,as it is universally practiced in all modern cultures.Someone just thought shaving made clothes look better; it became a fashion.
