I think she won't buy new palazzo pants leggings for the same reason she's still trying to stuff herself into the biggest sizes of standard line tops, even though they don't fit to the point of discomfort - most of her tops bind underneath her arms and strangle her arse, even the ones that are meant to be wafty. That horrendous maxi-dress is a great example.
But where she can grease up and squeeze into a top, comforting herself its "only" a 5x thereby one step up from the 4x that didn't fit previously, she's avoiding buying trousers because its been so long that she is not only not just jumping a couple of sizes, but probably about eight. Those ones are stretched to oblivion but in her mind "I still fit into a size 30" (or whatever they are) so she doesn't have to face the reality of her actual size. Amber's biggest problem is that she lies to herself and everything has to support those lies.
I couldn't get a grab, and made myself copiously sick trying, but when she has that horrific black....thing on, not only can you see through her leggings, you can see the crotch is pulling. She can't pull them up properly any more; the tops of the legs have stretched as far as humanly possible and they're binding. We don't ever see the insides of the legs, thank god, but I'd imagine they are one big hole held with a few threads, from the sweat and friction. They must be so uncomfortable, but obviously not as uncomfortable as facing reality.
Its that sort of hidden inner dialogue that makes me have feels for her occasionally. But then she does stunts like this recent YT stint throwing Becky to the wolves and kills any sympathy.
