I looked up the original summary Gematsu looked at and found the Japanese, so here's that and my translation:
ティファは腹筋を割りたかったのでアスリートスタイル。社内の倫理部署からの指示もあり激しいアクションで不自然にならないよう胸部を絞める必要があった。
そこで黒のアンダーウェアとフィットするタンクトップに

"Because we wanted Tifa's abs to be defined, she has an athletic style. Due to instructions from our Ethics Department, we needed to restrain her chest in order to avoid looking excessive and moving unnaturally. That's why [we gave her] black underwear and a fitted tank top."
So yes, your reading of it is correct!
