When you mean westward migration of people, do you mean across the Appalachian Mountains to KY, OH, IN, Louisiana Purchase, or do you mean from St. Louis, west to the Pacific? If you mean the first westward migration, that’s 1800 – 1840, which takes you into the settling of the TX Republic. If you mean across the Plains to CA, WA, OR, that would be from 1850 – 1880.
There were no zippers. Everything had button closures or hook and eye. Women’s clothing would be out homespun linen, woven from flax, or cotton chintz. the skirts were very full with petticoats, and the bodice of the dress very fitted. Often the top was as short fitted blouse that buttoned up the front. Women wore bonnets that were made of cotton for working in the fields or riding in the wagon. Men’s clothing was generally wool, because it was durable, with a coat and vest. Shirts had no collars and full sleeves. If a collar was worn with a tie, it was a detachable collar for dressing up. Men wore hats. Generally people only had one or two outfits, because clothing was stitched by hand. All laundry was done by hand so clothes were often not very clean.
