Body is private. Not shameful (God made it — so it's good). But private. Only for husband/wife.
Women
Dress to ankle (always). Sleeves to wrist (always). Hair under cap (after baptism — always). Décolleté — no. Form-fitting — no. Bright — no. Colors: blue, green, purple, burgundy (depends on community).
Men
Shirt (buttoned to neck). Pants with suspenders (belt = military = forbidden). Hat (straw in summer, felt in winter). Beard (after marriage — mandatory, mustache — forbidden).
Bathing
In the creek (children in underwear, not naked). In tub (in turns, one water for family — saving). Tub in closed room. Nobody sees. Even husband doesn't see wife naked (according to ex-Amish — in darkness, under covers, nightgown).
