Here is the example I was talking about

Also, the director in an AMA had this to say about the scene:
Q: What was the point of that topless scene in season? You know, the one where Nicky's girlfriend has some ultimately meaningless dialogue for thirty seconds while her gorgeous set is exposed for all to see?
Almost everything in the show, no matter how subtle, seemed to have a deeper meaning.
Was that just because she had great boobs?
A: She did. But how could we know they were that remarkable when we hired her from one fully dressed audition? The point was to show Nicky having an adult relationship but marginalized within his parent's rowhouse basement. The nudity suggests intimacy and familiarity between the two, and the surrounding suggests that their life together is not yet viable. Next in the sequence was a visit to a rowhouse in the neighborhood that they couldn't afford, if you'll remember.
