I cant stop thinking about how they very intentionally do not show all of Hannah's boobs.
She's either carefully cropped so her boobs are off screen, wearing a bra, or covered by sheets/Garrett in all of her sex scenes. They show Allie and Kendall's nipples in the first half of the first episode, but they NEVER show Hannah's. Kendall's tits we see when she's fucking Garrett. Allie's we see when she's getting undressed at home. Both are intimate moments.
Not having Hannah's nipples shown is honestly great symbolism for how she's hiding, uncomfortable with intimacy, and struggling to trust others with her whole self. We know Garrett sees her fully naked, but still the audience never does. She's trusting Garrett with all her truths, but no one else.
Not until the showcase. She bares herself to everyone through her music, not her body. And it's so FUCKING GOOD.
