Now what should we call republicans who have quit the GOP over Trump, and gone Independent or even Democrat? 
I'll send you a pm later today...Just have to go out now for a few hours. 
I fit it perfectly and use it as my designated form of formal address.
I am not a "Miss" since I am married. But I do not use my husband's surname so I am not a "Mrs." It is a battle I have waged since I married in 1977. I will NOT answer to "Mrs. Male Csziggy" because that is not me. I even had this disagreement with the IRS and the Social Security Administration. 
Here in the South "Miz" has been a form of address for any woman whether their married status is known or unknown so the transition to "Ms" may be more common than in other parts of the country.
Once in a while I get a negative response to it - most often when I address a woman as Ms. Whatever. Mostly it is married women who want to have that status recognized, but unless they introduce themselves as Mrs. Male Surname I will assume they are not attached to a male and use the indeterminate "Ms."
Mr., Dr., Ms, Mrs, Miss, etc. At least now they do include Ms - that is an advance. Yeah, it would be nice if none of the forms were determinate as to marital status but I would not advocate that men have the limitations that women do, just that women accept one form that is indeterminate.
That's why I like the Southern "Miz" - when it was used extensively, it included all women without determining their marital status. But it was also associated with slavery and black oppression which I believe is why "Ms" (pronounced "miz" was introduced.
I think it is a style of business courtesy to use a title for customers - even when the salespeople call us by our first names even when we've asked them not to.
For some reason I get called "Miz firstname" by all sorts of people, usually those younger than me who I've asked to just call me by my first name. Even when I have told people that I don't use my husband's surname, they often call me Mrs. mysurname. And of course, my husband gets called Mr. mysurname very often.
The part that really pisses me off is companies that decide that a woman MUST use her husband's surname or those who translate a married woman to being secondary to their husband.
The IRS started it - well maybe our first accountant did it. Since I had the main income I listed myself first on the documents. But the accountant switched our name because of "male must be head of household" - but the idiot did NOT switch the Social Security numbers. So we got a letter from the IRS saying our Socials were wrong. I wrote back and explained the mix up, no problem, or so I thought. Then I get a letter from Social Security asking why I didn't notify them of my name change. I wrote them a testy letter telling them I did NOT change my name and that the IRS format on their forms (first name of head of household, full name of spouse, last name of head of household) screwed up. I've had no problem with the Social Security offices since.
When we changed accountants we had no trouble with him but his asshole bookkeeper couldn't handle it. Every single piece of correspondence was addressed to Mrs. myhusbandlastname until I raised Cain with her boss. The last time I ever had any interaction with her, she called and tried to talk me into selling Avon. She looked sort of like that woman from The Office while I do not and never have worn makeup. Why the hell would she think I might even consider selling that crap? I called her boss and told him what she had done. He made sure she was no longer on my paperwork. She did work at his office until he retired, but a different person took care of me until then.
I've been through pretty much every iteration of trying to assign a woman to secondary status to a man. I chose my battles carefully now. But as my husband says, don't get me angry, I will pin my grudge on the wall and throw knives at it. 
I think that whole mess was why the IRS audited us four years in a row.
They are worse about grudges than I am. 
I still have the main income, ran the main business we had for the most years, and do all the bookkeeping (with Quicken now). Now I kinda love when idiots call and want to talk to my husband rather than me. He seldom has the answers to their questions so has to turn them back over to me. If it is not essential and I am in a bad mood, I just tell them, "You didn't want to talk to me" and hang up.
I'm at the age where I just don't give a shit anymore.
The father said David loved men and he loved women and he loved men who became women and he loved women who became men. He was a "pan-sexual". He just loved people.
