This is a picture of the first Tramp and Trail Hike in 1921. Note the clothing!

Women did not yet have the right to vote, but they were hiking!!

They wore old street clothes. In 1921 that meant long full skirts and coats; shirtwaist; and silk, straw or felt hats trimmed with ribbons and flowers and old street shoes. Later they bought “brass/leather boots” at $8 or $10 a pair.

Skirts were the biggest problem. It was inappropriate to appear on city streets without a long skirt but impossible to climb in them. As a result, a woman wore knickers (knickerbockers /ˈnɪk ərˌbɒk ərz/, loose-fitting short trousers gathered in at the knees) under her skirt, and on leaving the city she placed the skirt in her knapsack until her return trip through the city. By 1924, some of the more daring woman wore only the knickers with long socks, and despite the stares of some city folks the trend continued.
