the script will remember it till the end of the story - you just have to make sure that any other of your choices isnt named like this one
choice (OUTFIT_1)
so if you will use this template next time change the name of the choice to for example
choice (OUTFIT_2)
the only “problem” is that portal where you write doesn’t remember choices from previous chapters because the portal works bit differently than the app. But when you will test it in the app it will remember it.
