Body adornment is one of the changes that occurred in the late Paleolithic (40,000 to 60,000 years ago) that indicate that humans had become not only anatomically but culturally and psychologically modern, capable of self-reflection and symbolic interaction. Fashions in ancient Egypt changed little from its beginnings until the Middle Kingdom. The ancient Egyptians wore the minimum of clothing. Both men and women of the lower classes were commonly bare chested and barefoot, wearing a simple loincloth or skirt around their waist. Slaves and laborers were nude or wore loincloths. Nudity was considered a natural state. During the Early Dynastic Period, (3150–2686 BCE), and the Old Kingdom, (2686–2180 BCE) the majority of men and women wore similar attire. Skirts called "schenti"—which evolved from loincloths and resembled modern kilts—were customary apparel. Women of the upper classes commonly wore a "kalasiris", a dress of loose draped or translucent linen which came to just above or below the breasts.. Women entertainers performed naked. Children went without clothing until puberty, at about age 12. In the First Intermediate Period (2181–2055 BCE) and the Middle Kingdom (2055–1650 BCE) clothing for most people remained the same, but fashion for the upper classes became more elaborate. During the Second Intermediate Period (1650–1550 BCE) portions of Egypt were controlled by Nubians and by the Hyksos, a Semitic people. During the brief New Kingdom (1550–1069 BCE), Egyptians regained control. Upper class women wore elaborate dresses and ornamentation which covered their breasts, often represented in film and TV. Those serving in the households of the wealthy also began wearing more refined dress. Third Intermediate Period (1069–664 BCE)  Late Period (664–332 BCE)  In some ancient Mediterranean cultures, even well past the hunter-gatherer stage, athletic and/or cultist nudity of men and boys – and rarely, of women and girls – was a natural concept. The Minoan civilization prized athleticism, with bull-leaping being a favourite event. Both men and women participated wearing only a loincloth, as toplessness for both sexes was the cultural norm; men wore loincloths, whilst women wore an open-fronted dress. Ancient Greece had a particular fascination for aesthetics, which was also reflected in clothing or its absence.
