A detalle, a detail, is a small part that adorns or completes the look of something, as in arreglar una casa con muchos detalles, to fix up a house with many details. It is also a gesture of delicacy, courtesy or attention: “Tuvo el detalle de hablarme para desearme feliz viaje” (He had the detalle of calling me to wish me a good trip). A detallista cares about details.
Arreglarse, to fix oneself up, means to take care of one’s appearance “para lucir bien o tener buena presentación” (to look good or to have a good presentation). Lucirse, to shine, means to win the attention and esteem of others with a successful performance: “Los alumnos se lucieron ante el inspector” (The pupils shone before the inspector).
Estar de manteles largos, “to be in long tablecloths,” means to prepare a meal with luxury and abundance to celebrate an event. Estrenar is to use something new for the first time. México Desconocido writes of New Year’s Eve: “Es común que todos estrenemos ropa para vernos guapos” (It is common for all of us to wear new clothes to look good).
