So basically here, simply, as explained to me by a nice person in the comments, this is talking about why nurses are offended. So the outfit Jennie is wearing isn’t the one nurses wear today- it’s the old one, outdated. Korean nurses fought to change the outfit originally cuz+ https://twitter.com/gatamchun/status/1313795788527542272

Nurses in the field aren’t very well respected, in the past and still today they would often be victims of sexual harassment from patients. So this is saying Korean Nurses associate this old uniform with that history because it was a catalyst for sexual harassment at the time+

So my view is that Jennie wasn’t at all trying to be sexy in the MV or insinuating anything, and this is what I think this thread is trying to say is it’s due to the uniform being associated/rooted in misogyny and sexual objectification that nurses want it taken out.

Though, I do have to wonder many girl groups have done similar concepts/worn nurse outfits too, so why didn’t they speak up then ? Idk tbh?? But given the time rn I do kinda(?) see why they would want to due to them facing the pandemic and working more.
