Answer:
Ella usa vestidos elegantes.
Explanation:
She wears elegant dresses.
She = Ella
Wears can be translated into uses, so "to wear" conjugated into he/she/you (formal) form is usa.
Dress is usually "vestido", however, since it's plural, dresses = vestidos.
Adjectives come after a noun in Spanish, as well as takes a plural or singular form accordingly, so elegant in this scenario = elegantes.
Ella usa vestidos elegantes.
