Sie hat immer sehr elegante Blusen und Hosen.
From answers to this question I understand that for the above sentence the adjective takes the ending -e and not -en because of strong inflection.
What does the ending of the adjective become when it is applied to two nouns that are different genders?
My chart does not help me in the following example:
She always has a very elegant blouse and belt.
Since blouse is feminine (die Bluse) and belt is masculine (der Gürtel), what does elegant become?
