I think the Amazon corset trend person might have been talking about either the viral videos of girls tightlacing each other before parties (usually a before&after + reaction) or else the meme with the snippet from the Haus of Holbein song from Six! the musical, which is sometimes done with tightlacing and other times something along the lines of Spanx/Skims.
That is one of the stupidest things I've ever heard.
Protip: if you want to waist-train comfortably, do it over time. Bit by bit, so your body gets used to it and you can adjust anything that doesn't feel right. If you're an adult, it's a valid form of body modificatin (and mostly temporary, as I understand it; it can reshape your floating ribs a bit, but not in a way that will cause harm), but for the love of god do it right. don't try to crunch yourself in all at once- you can still look impressively stylized in silhouette with only an inch or so of reduction, because of how the fat is redistributed. I've been told my waist looks "snatched" in a corset that literally cannot take me down more than an inch (from 28" to 27", so still not even remarkably small in measurement for someone who's 4'11")
also not in an. Amazon corset. are you insane? are you trying to get stabbed with scrap metal boning? because that's how you get stabbed with scrap metal boning
(also also I hate that song. they're radically misunderstanding the nature of court paintings- sure, they were a bit filtered in modern parlance, but they were still supposed to be a decent likeness of the person. and corsets didn't exist back then. I don't think their earliest predecessors, pairs of bodies, had even made the scene. the support garment of choice was a kirtle with a stiffened bodice, and I'm not sure anything resembling tightlacing could even be done in one of those)
