Just thought of this: Many, many years ago, reading/watching a DIY. If we want to have shirt type of dickies, go to the young men's or boy's dept., buy shirts there, and cut them out so they are dickies. Might want to try thrift shops, too. Sometimes they have almost new/brand new shirts that perhaps wouldn't be our complete size, but can be used as a shirt-dickie/dicky. I think the theory there was that sometimes young men's/boy's shirts are less expensive. (Or something similar, lol).
'More or less', 'Right or wrong', 'In general', and 'Just thinking out loud ' (as usual).
