For an idea ever to be fashionable is ominous, since it must afterwards be always old fashioned

Good, old-fashioned ways keep hearts sweet, heads sane, hands busy.

I'm a little old-fashioned.

Status based on wealth is an old-fashioned idea; I find it repugnant, actually.

To say that an idea is fashionable is to say, I think, that is has been adulterated to a point where it is hardly an idea at all

We'll have to wait the old-fashioned way.
