Ms. vs Miss. for early 30's

Ms. For all unmarried ladies.

Miss applies more to very young girls, like 16 and under. Ms is more appropriate for all others.

No Miss for anyone over the age of 15.

I used Ms. for all unmarried women.

Ms.

Yup, no miss after they're adolescents. You're probably okay up to 16 or max 18, but that's it.

Thanks everyone!

I've always gotten Miss on all invites...I'm 34

I think this is regional. I prefer Ms but just got an invite with Miss on it and FH's 29 year old sister put "miss" on her RSVP...just to make things complicated. I'm in CA and they are both east coasters.

I just put their names. I hate Miss and Ms. And my invitations were casual.

This is HUUUUUGEEEE pet peeve of mine. My supervisor at work always address stuff to me as Miss and it drives me crazy. Miss is for girls (under 18). Ms. is appropriate for unmarried women (18+)

I use Miss for anyone who has never been married. Ms. is for someone in a professional setting or a divorced woman.

eta: honestly i did both , and i dont think that unless you have a "pet peeve" about the title that anyone would even notice. Both are correct unless there is a personal preference on which one to use. Ms. is essentially an abbreviation of miss.

Ms. is used when you dont know what title to use also

When I took my etiquette class (yes there was such a thing) we were told:

Ms. is for a woman who was married but is no longer married and/or over the age of 25

Miss. is for a woman who has never been married and under the age of 25

It may be regional, but I grew up in Silicon Valley, and anything addressed to 'Miss' after I left hgh school would have just made me laugh. I think 'Ms.' is a safer bet.

I'm from the east coast and I would say Ms. For your guests. Miss. Is for children

Miss for girls under 21 (or 18 or 16).

Ms. for all women -- whether single or married. Unless you know they prefer "Mrs."

Miss for girls under 21 (or 18 or 16).

Ms. for all women -- whether single or married. Unless you know they prefer "Mrs."

Miss for a girl of an age that you'd use "Master" for a boy.

Ms. for all other females, married, single, divorced, or widowed. Mrs. can properly be used only with the husband's name for a married woman or a widow. (Mrs. John Smith) And really, you don't want to stir up that whole hornet's nest!

I just did names like John & Sue Smith - no Miss, Ms. or Mrs. mess there.

Miss is used for unmarried girls/women of ANY age.

Ms. is a (relatively new) politically correct term of address for women equivalent to "Mr."-- i.e., it does not denote marital status.

Ms. is primarily for business purposes, but some women certainly prefer it for various reasons-- I'd probably stick with that just b/c you're sure not to offend anyone, but I am surprised by all of the confusion tying the titles to age. .. that's just not the case at all. . . .
