Alot of things can effect the "size" and "shape", Water intake / Exercise / Muscle / Temperature / Monthly cycle..I expect a lot of dudes don't understand how tits work, but they haven't been enlarged whatsoever.
It's just her normal clothes bind them a lot better since they're sports oriented, and the cleavage is a lot smaller. The size is the same, and the bikini pull them a bit closer together so they look a bit more elevated.
Maybe I'll be alone in this over here but the last thing Square's going to do is kowtow to dudes who care about that kind of thing and I'm happy about that lol. They're clearly actively trying to veer the character away from objectification.
That being said most people just go ooo big bouncy bajongers!
Now back on topic of the thread..
I am happy to see the dev teams hard work paying off and hopefully Most/All of them get some time off.
