Still have a few questions? Not sure when to use Miss vs Ms.? We’ll explain everything you need to know about using formal titles, like Miss, Ms., and Mx., including which to write when addressing your wedding invitations.

Miss vs Mrs. vs Ms. vs Mx.: The Key Differences

The key differences between all of these terms revolves around a female guest's marital status. Miss is typically reserved for young, unmarried women; use Ms. if Miss feels too juvenile, but the woman is also unmarried. Mrs. is used for married women only—and Mx. has become the honorific of choice for those who are non-binary or want to avoid a gendered term. This is a good option for loved ones who use the pronouns they/them.

Miss Meaning

Use the prefix Miss to address young unmarried women or girls under the age of 18. Technically, any unmarried woman can be referred to as Miss, but the title can feel a bit juvenile and immature when addressing women of a certain age, or women who’ve been divorced.

It’s sticky situations like these that make Ms. the clear best choice, especially in a formal setting. For young girls under the age of 18, it’s perfectly acceptable to refer to them as Miss. If you have to question it, go with Ms.

Ms. Meaning

Ms. is the proper way to describe any woman, regardless of her marital status. It’s a catch-all, neutral term that came about in the 1950s as women began to assert their desire to become known for something outside of their marriage, and took hold in the 1970s with the women’s rights movement.

Ms. is pronounced mizz like quiz, not miss like kiss. It’s considered the female equivalent of Mr. and can be used in any setting to refer to an adult woman. Married women are often referred to as Ms. in a business setting where marital status isn’t known or seen as pertinent, but it’s most often used to describe women who aren’t married since Mrs. refers to married women and Miss relies heavily on age. If you’re not sure if a woman is married, or if she's divorced, it’s safe to go with Ms.

Mrs. Meaning

The prefix Mrs., pronounced missus,is used to describe any married woman. Today, many women decide they want to keep their last name instead of taking their husband’s. These women are still referred to as Mrs. A widowed woman is also referred to as Mrs., out of respect for her deceased husband. Some divorced women still prefer to go by Mrs., though this varies based on age and personal preference.

Traditionally, this title would accompany the husband’s title, first and last name (Mr. and Mrs. John Smith), although this practice is becoming increasingly less common. Use this title of respect to address married women, or when speaking to a woman of authority to show deference.

Mx. Meaning

Pronounced mix or mux per Merriam-Webster, Mx. is a gender-neutral honorific title. This prefix is suitable for those who are non-binary or use the pronouns they/them. As with all title preferences, it's best to ask someone what their preferred pronouns are if you're unsure.

Addressing Wedding Invitations With Miss, Mrs., Ms., or Mx.

Addressing wedding invitations is just as important as the information on the invite itself. Your guests are important to you, which is why they’ve been chosen to attend in your special ceremony. Using what you now know regarding the differences between Miss, Ms., Mrs., and Mx., address the outer and inner envelopes with the proper title.

When and How to Use Miss

• For young girls under the age of 18, use Miss.
• Have her name follow the name of her parents if also invited (Mr. and Mrs. John Smith, and Miss Janet).
• The plural of Miss is Misses.

When and How to Use Ms.

• When inviting an unmarried adult woman, or if you’re not sure if she’s married, use Ms.

When and How to Use Mrs.

• If a woman is married, use Mrs.
• If you’re inviting a couple, it’s up to you if you want to refer to the names of each after their respective titles (Mr. John and Mrs. Jane Smith), or simply use both titles along with the husband’s name (Mr. and Mrs. Smith). The latter is more formal, but be cautious if you’re not sure if the woman decided to keep her name.
• If you’re only inviting a woman, and she’s married, use Mrs.
