I, Fabiola, spent the last several days working on railroad track. Rather advising Mary as SHE worked on the railroad track. Fabiola was much too concerned with keeping her bib-alls in order. In the event that you are contemplating wearing railroad duds, Fabiola would like for you to keep these items in mind.Striped blue bib-alls are for engineers. If you don't drive a train and wear stripes, you risk having some old gentleman point out that you shouldn't be wearing them. If you Do happen to drive a train and some old gentleman tries to take you to task for striped bib-alls, you get to make snarky remarks.
Iron your bib-alls, wiggly stripes give people motion sickness.
All those pockets and loops on bib-alls are for tools, tools are for work, work gets just ironed bib-alls dirty, leave the pockets and loops empty. The only exception to this no tools rule is that you may lean on a spike puller. Unless you are wearing plain blue bib-alls, then you could be pretending to be a farmer, and you would lean on a tractor.
If your bib-alls are green, then you are a character on Captain Kangaroo and not likely to need Fabiolas fashion advice.
