Just looking for opinions for wearing on strap off as I am thinking about doing that from now on.

No...don’t

Does anyone wear overalls with only one strap up?

Wearing overalls with one strap undone looks pretty "unbalanced" and sloppy. Also, if someone sees your overalls and wants to buy a pair for themselves, they won't know what brand they are, because they won't be able to see the tag on the bib!

Gotcha! Just getting opinions is all. I wear shirt shirts with logos on them and folks have suggested the idea so the logo on shirt is shown.

So if you are wearing a shirt with a logo, how will you determine which overalls strap to leave unfastened (left or right)?

I am thinking the left if I do it.

I will wear all overalls with left strap undone so logo shirt can be seen just like photo

And left strap will hang visibly behind me. I like it.

Or if you wanted the whole shirt to be visible, you could unfasten both straps and the left and right strap would hang visibly behind you.

I cannot go that far as they will not stay up. I like it better just wearing one strap. More comfortable. Thanks for suggestion though

How do you get the bib down far enough to display your shirt? Do you fold and crease the bib? When I unfasten my other strap, the bib tends to still stay up on my chest.

If you want the shirt to show maybe wearing both straps down is the solution.

Put your overalls on and fasten only one strap. Let the undone strap dangle behind your back. Then take the unfastened side of the bib and fold the bib down diagonally over your chest.

It's not that hard to do. For example, here is a selfie of me wearing dungarees with part of my shirt showing.

Wow, that's awesome! Just like this teen.

How does the bib look when you wear your overalls with one strap undone?

Does the bib stay up, does it fold slightly or does jt fold more than half way?
