I'll admit, it'd be cute to watch a slice of life about the skittish girl and her seamstress boss trying to run a small clothing shop with all sorts of characters coming in wanting outfits for different reasons and occasions. They'd sit with the seamstress who'd slowly get them to open up about their backstory while taking their measurements and the girl would slowly come out of her shell and grow as a person through her encounters with these customers, some of whom come back and even become regulars!
It'd be a cute thing to see, is all.
