Explanation:

In Spanish, the imperfect tense of the verb "llevar" (to wear) is used to describe ongoing or habitual actions in the past. "Llevaba" is the imperfect - tense form. "Llevó" is the preterite tense (used for completed actions in the past), and "lleva" is the present - tense form.

El ladrón llevaba pantalones negros.
