The Darkest Minds and the Bras: Part 2

I am at 70% or so, and bras made another appearance. Ruby finds piles of them in an abandoned and looted Walmart. Which makes perfect sense to me: who needs bras when you should be getting food? But then…and that’s where I got confused…then the book tells us that Ruby digs through those piles to find a new bra for herself because…I don’t know…her boobs are falling off? I mean it’s hard to believe that a girl who has just escaped from a sadistic concentration camp would care so much about her appearance…but then again, she does shave her legs on the FIRST DAY of her escape from the camp.
