FI, I would simply resist the urge to comment on people’s size at all, even under the guise of “culture.” I celebrate any move from designers or retailers to fit a wider variety of bodies. Period.
I am personally trying to move away from body comparison and talk of size/weight, as it tends to be unproductive and possibly hurtful. As someone who was on the receiving end of a recent body comparison here on YLF (which made me feel like the before in a “before and after” ad), I urge people to keep the conversation to style, not bodies.
