Portable Teepee
In one of Izzy’s favorite episodes of Curb Your Enthusiasm, the neurotic protagonist is highly annoyed by extra trouser fabric bunching up over his crotch. But the “pants tent,” as Larry David calls it, is a phenomenon that occurs only when he sits down, which makes the ill-fitting crotch on these Banana Republic trousers even more inexcusable.

As someone who sews, I can say for a fact that this is a fit problem: it’s caused by a zipper that is too long and/or a crotch length that is too long, or both.
My mother (teaching me how to shop for clothes as a young girl) regarding pants with this problem would say, “Those pants don’t fit; they’re smiling.”
I think it’s hot.
