The head-covering question is the single most common thing non-Jewish guests Google before a bar mitzvah. The answer is short for men and slightly more complicated for women, but neither version should stress you out. Synagogues are used to guests not knowing the rules, and the rules themselves are forgiving in practice. Here's the honest version.
Men: yes, wear a kippah
A kippah (Hebrew) or yarmulke (Yiddish) is the small round head covering worn by Jewish men during prayer, Torah study, and inside a synagogue. For a bar mitzvah service — and often at the party as well, if there's a motzi blessing over bread — men cover their heads. This is true across every denomination from Reform to Orthodox.
The good news: the synagogue will have a basket of kippot at the entrance. You don't bring your own. You don't need to know your size. You walk in, grab one off the basket, put it on, and you're correctly attired from a head-covering standpoint.
A few practical notes:
- It stays on the whole time you're inside the sanctuary. Don't take it off when you sit down. Don't take it off for photos.
- The clip provided (usually a small bobby pin or kippah clip in the basket) keeps it on your head. Use one if your hair is thin or short. Two if it's slippery.
- Bald guys: you'll need a clip or it will slide. Or the synagogue may have suede kippot with a slightly grippier underside — those stay on bare scalps better than satin ones.
- You wear it at the kiddush luncheon and at the Saturday-night party too, if there's a motzi (blessing over bread) at the meal. At a more casual Sunday brunch, you can usually take it off after the motzi.
If you have your own kippah from a previous event, you can wear it. The synagogue's kippot are functional, not a uniform.
What if you don't want to?
If you decline to wear a kippah at an Orthodox or Conservative synagogue, you'll be politely but firmly asked to put one on. Don't make this a thing. At a Reform synagogue you may technically get away with not wearing one — Reform doesn't require head coverings for men, though most men wear them anyway as a matter of respect. Just wear it. It costs you nothing and signals respect to the family hosting you.

Women: it depends on the synagogue
For women, head-covering rules at a bar mitzvah split sharply by denomination and by the woman's marital status. Here's the breakdown.
Reform synagogues
You don't need to cover your head. Many Reform synagogues offer kippot for women at the entrance, and some women take one, some don't. Either is fine. There's no expectation.
A few Reform women specifically choose to wear a kippah as a feminist statement of equal religious participation. If you're a guest, this is entirely optional and stylistic.
Conservative synagogues
Norms vary. Most Conservative synagogues now offer kippot for women at the door and most women take one. Older Conservative congregations may still default to women uncovered. Wearing a kippah is welcome but not required. A hat or scarf is also acceptable.
If you're not sure, watch what other women are doing as you enter the sanctuary. Match them.
Orthodox synagogues — unmarried women and girls
In Orthodox synagogues, unmarried women do not cover their heads. This includes teenage girls, single women of any age, and the bat mitzvah girl's friends. Nothing on your head is the norm.
Orthodox synagogues — married women
Here's where it gets specific. In Orthodox practice, married women cover their hair (this is the law of kisui rosh). At synagogue this typically means:
- A hat (any tasteful style — fascinator, beret, wide-brim, beanie depending on season and formality)
- A scarf or wrap (often more common in Modern Orthodox; widely accepted in Yeshivish)
- A sheitel (wig) — most common in observant Orthodox communities, especially Lubavitch and Yeshivish
If you are a married guest at an Orthodox bar mitzvah and you don't normally cover your hair, bring a tasteful hat or wide scarf. A simple wide-brim hat that matches your outfit works. You're not expected to wear a sheitel.
If you're not married and you're being directed to cover your head at an Orthodox synagogue, something has been miscommunicated — that's not the norm. It's safe to ask the synagogue host or the family which expectation applies. They'll resolve it in 10 seconds.
Conservative-Egalitarian synagogues
A subset of Conservative synagogues are explicitly egalitarian, meaning the practices women do are the same as the practices men do. At these synagogues, women often wear kippot, and sometimes talitot (prayer shawls). If you're a guest at one of these, taking a kippah at the door is the most common move.
If you're not sure what category your synagogue is, browse synagogue listings — the denomination tag tells you most of what you need.
The bar mitzvah party (not the service)
At the Saturday-night party or Sunday brunch reception, head-covering rules generally relax. Specifically:
- Men at the party: a kippah is worn for the motzi (blessing over bread) at the beginning of the meal. After that, in Reform and most Conservative families, men can take it off. In Modern Orthodox and more observant settings, men keep the kippah on the entire meal.
- Women at the party: whatever you wore for the service is fine for the party. If you brought a hat to an Orthodox service, you can take it off for the party in most cases. (Lubavitch and Yeshivish weddings are more strict; bar mitzvahs are slightly looser.)
For phone use during the service, see phone etiquette on Shabbat if it's a Saturday morning event.
Non-Jewish men and women: same rules
Being non-Jewish doesn't exempt you from head-covering practice in a synagogue. The kippah at the door applies to you the same way it applies to a Jewish guest. Wearing one is not a religious commitment, conversion, or signal of belief — it's respect for the space you're entering. Wear it.
The same applies for women. If the synagogue expects married women to cover their hair, that expectation applies to non-Jewish married women too. Bring a hat or scarf if it's an Orthodox event.
For more on non-Jewish guest expectations broadly, see the non-Jewish guest etiquette guide and whether you need to be Jewish to attend.
The 30-second rule
If you have any uncertainty about a specific synagogue's expectations, email the synagogue office or text the family. Sample message: "We're so excited to be there Saturday. Any specific dress-code or head-covering norms we should know about for [synagogue name]?"
You'll get a clear answer in under an hour. Synagogues field this question constantly and have well-rehearsed answers. The family will appreciate that you asked.

The short version: men, kippah, every time, provided at the door. Women, it depends, ask the family if you're unsure, and bring a hat if you're a married guest at an Orthodox shul. That covers 99% of the cases.
