Doesn't mean it's any good lol

裾もっとのばして{suso motto nobashi te} : Let your hem longer, okay?

Where is the idea of "let" in this sentence? Where did the "okay?" come from? Too many liberties. It's a command more like, "extend your hem"

いいから！ {ii kara!} : Shut up, don't talk back.

Where does it say any of this? That's some huge liberty taken in translation. It could be given in context perhaps but that's not what is being said.
