Tifa has a highschool AU costume being released in FFVII Ever Crisis. Her earring is a chocobo charm with a heart, and her bracelet has a bomb charm.
Tifa’s outfit in FFVII Remake Trilogy includes two charms; a chocobo and a bomb. These represent Cloud – the chocobo – and Tifa – the bomb as in bombshell. This is confirmed in a sidequest from Chocobo Sam where he says Tifa is a bombshell just like the enemies you come across in the game, a play on words.
Also in Gold Saucer, you can obtain a chocobo plushie and a bomb plushie. If you do and start Johnny’s treasure sidequest, these two items are always together in the collection no matter how you play it.
Update:
Since the event has been released, it has since been discovered Tifa is also wearing a chocobo bracelet on her left wrist, same as her Remake outfit!
