It is tradition in Mexico to host a large party on a girls 15th birthday called a quinceañera to celebrate her transistion from child to young woman. The closest thing we have in American culture is a girl’s sweet sixteen.
When I was young, my family attended a quinceañera and I was blown away by how grownup the young woman looked in her mother’s wedding dress and loved the rhinestone tiara that she wore. So beautiful! 😍
