A lot of it is actually just having to do with the necessities of motherhood, the need to feed your child and breastfeed. And then that’s kind of juxtaposed, later, when Margo’s doing her OnlyFans. But I think it’s a nice commentary of how her relationship to her body changes.
Examples from the OnlyFans portion of her life:
You can find examples from the pre-OnlyFans period in the first three episodes, which are covered in depth (with captures and videos) here.

We’re pretty pleased as well
INDEED!!!!!!!! DAT ASS!!!!!!
Really loving the series three episodes in. Applaud Michelle Pfeiffer for playing a parody an aging woman who doesn’t want to admit it. She was a Hooters waitress who married a pro wrestler….the most American love story ever.
lol. the screenshot i posted is still making its way around.
