Can’t speak for the OP, but I would say almost all of it is, yes. I mean, if summer fashions tend to involve lighter-weight fabrics and fewer layers than winter fashions in the US, that fact probably can be explained without reference to signaling theory, but that’s the exception.
Does this means all fashion is signalling ?
What? Yes, of course. It is close to the epitome of pure signalling!
What else could it be?
