I don't care about fashion one way or another. I understand that it is a kind of art that is not supposed to be appreciated in the sense of "real people actually will wear this specific outfit". A lot of it looks completely ridiculous, but I understand that there is artistic merit (which I have no grounding to appreciate, or any real interest in) to it outside of what it looks like if you imagine someone on the street wearing it.

Which is why it seems to me like "that looks silly" isn't a valid thing to say at a fashion show in the first place.
