My wife does things like this. She modifies clothes and wears them.
She has a bra that she slides ice packs in because her beasts get too hot sometimes? She has a special shorts with the thigh slits because when she gets chafing? There's some others.
I don't think we have a community like r/AltBoobWorld (NSFW) in the Fediverse. Surprisingly wholesome.
Maybe someone should contact their moderators and get them to join lemmynsfw.com – they partook in the API protest, after all.
