"...the mechanics, the farmers and the labourers dressed in their Sunday best..."
Here's a wonderful depiction of small town Iowa life around the turn of the 20th Century, from Sherwood Anderson's Windy McPherson's Son:
Saturday night was the great night in Caxton life. For it the clerkgs in the stores prepared, for it Sam sent forth his peanut and popcorn vendors, for it Art Sherman rolled up his sleeves and put the glasses close by the beer tap under the bar, and for it the mechanics, the farmers and the labourers dressed in their Sunday best and came forth to mingle with their fellows. On Main Street crowds packed the stores, the sidewalks, and drinking places, and men stood about in groups talking while young girls with their lovers walked up and down. In the hall over Geiger's drug store a dance went on and the voice of the caller-off rose above the clatter of voices and the stamping of horses in the street. Now and then a fight broke out among the roisterers in Piety Hollow. Once a young farmhand was killed with a knife.
In and out through the crowed Sam went, pressing his wares.
So many nice touches there: crowds wearing their Sunday best, but on Saturday night; fights in Piety Hollow; the abrupt murder of a farmhand, told in a casual, almost matter-of-fact manner. And throughout, teenager Sam McPherson selling selling selling, working the crowd without ever really being part of it.
