Historic photographs indicate that in the decades before they became a staple of fashion, jeans generally fit quite loosely, much like a pair of bib overalls without the bib.
" Now let us go home, and never mind Aunt March today. We can run down there any time, and it's really a pity to trail through the dust in our best bibs and tuckers, when we are tired and cross."
She longed to run home, bib and all, and ask Mother to lend her a hand, but John and she had agreed that they would never annoy anyone with their private worries, experiments, or quarrels.
