"She wears a purple dress."
Translation:Porta un vestito viola.
I imagine it's the same as it is in Spanish. To carry or to wear in Spanish is "llevar," so this must be the equivalent (for using the word) in Italian. Llevar would be used for to deliver, to bring, to wear, to cause. There are some handy Italian dictionaries online that I use to take notes from -- mainly the different ways they can be used in sentences.
