I'm sorry bc i am late , lol.
I praised Michele and im going to praise him again because :
Seems that this interview was in english? Alessandro doesn't speak perfect english.
It is not easy to find the right words to describe your thoughts and your feelings, sometimes it is even not easy if you are speaking in your mother language, so imagine if you have to speak in foreign language.
I remember last year was Jared Leto and Michele live on Instagram, i saw them, it was some kind of converstation/interview between Leto and Michele, believe me, Michele's english wasn't so perfectly fluent, sometimes he used italian words because he didn't know to explaine himself in english.
It is clear what he meant under "ghetto" or "borgeois" ,in this moment i can imagine the look which could match with this description, is could be a trackpants with a silk blouse and pumps or tracksuit in jacquard or embroiedery.
It is my opinion.
And if somebody saw this live on Instagram , it was end of 2017 or in 2018 ,when Leto wrote an article about Michele, he/she remember that Michele's english wasn't so perfect. So same in this interview. Imo.
