> Ms or Ms.
> Miss Lisa Simpson (under age 18)
> Miss Lisa Simpson (age 21, soon to be married)
Ms. should be used as the slightly formal honorific for all women over the age of 18, regardless of marital status. Use Ms. when you are writing notecards on both the note salutation (with last name only) and the address on the envelope (with first and last name).
> Dear Ms. Simpson, (salutation)
> Ms. Marge Simpson (on envelope)
123 Main Street
You may also use Mrs. along with the last name as long as you do not use the woman's first name. Mrs. should never be separated from the man's name. Ms. is always acceptable for married women, so feel confident in defaulting to Ms. if you are not sure of marital status. I use it as a slightly formal sign of respect, although be cognizant that very formal acquaintances, especially society women of the south, will appreciate the formality of only addressing them as Mrs. followed by their husband's full name.
> Mrs. Butler
> Mrs. Rhett Butler
> But never Mrs. Scarlet Butler, only Ms. Scarlet Butler
