A Bat Mitzvah is a Jewish coming-of-age ceremony for girls, marking their transition into religious adulthood at age 13. The ceremony typically includes being called to the Torah to recite a portion (Aliyah), delivering a speech (D’var Torah), and participating in synagogue services. It is often followed by a festive celebration with family and friends. 

Attire for the service should be modest and comfortable (think no jeans or shorts) and please cover shoulders.
