The nanny turning out to be a lesbian and thus allaying all charlottes fears that Harry might cop off with her- I felt the storyline the last episode of AJLT was reminiscent of that. Charlotte was stressed about not looking good in the dress with the belt, and eventually bought a load of Spanx, but as soon as she met the leader of the gallery she felt absolutely fine about it, because the lady was on the larger side and had a grungy style. At once Charlotte felt confident and comfortable with her body and new outfit, and binned the Spanx (how bloody wasteful!!)
So my take on it was all you need is someone who doesn’t look as good as you in your opinion and voila.
