>>21337468Ame matches her outfits to the theme of the stream, a Detective game will ALWAYS get her to wear her OG outfit. An Action game usually is involves the coat, with or without hat. Watchalongs, Zatsus, Supa readings more often than not are on her casual outfit. Pokemon Arceus had her kimono because the game has ancient japan aesthetics.
There are very few occasions that require a full on night dress, maybe if she played a game about princesses? New Years, Kingsman could be an opportunity if she knew what the movie was about but she might not know and just use her casual outfit.
Of course this is not a set in stone rule, like when she played Halo in her night dress or using the pink edit for Valentines, etc. But i would say that in 70% of the cases you can guess which outfit will Ame use by the content of the stream.
