Jelly-jiggle physics, wow. That's depressing.
As an aside, it's like the team are so afraid of poor Tifa having the slightest possibility of muscle definition in her shoulders and arms that there's this weird skin ripple/deformation on her pectoral muscle near the armpit. It's less apparent when she's standing up straight, but when she bends forward it's noticeable. I feel like it's intended to be the muscle and fat that naturally sit there, but because Tifa has so little muscle, it's not quite working. For quick reference, it's easier to quickly see in stills.

It's there from the beginning of the gif, but you can see it when the gif pauses at the end (that's one hell of an accompanying tweet):

I feel extremely weird mentioning it, but it was also really bizarre to notice, too. Tifa can be hot as hell in a bikini without the extra level of breaking basic anatomy -- or terrifying jelly physics.
It's really odd, yeah. Take way the frills and it seems like there is a potentially a nice sporty, striped bikini there somewhere. She's even got a matching striped wristband!
Between FFVII+OG Wall Market dress + AC, I always thought Tifa was about sleek and sporty, but FFVIIR felt like it was throwing everything at the wall with her outfits. Aerith is more stylistically consistent, though admittedly always in something pink with FFVIIR.
