I've cut the pattern and started sewing and I have to say that it's not exactly a top hat, it's significantly shorter than that (something I'm tankful for, since sewing it is already unwieldy as is :) )
But is has all of the parts of a top hat, and I'm following instructions that could, with a wider crown side, result in a top hat (the milliner version in fabric over a buckram and wire structure, not the hatmaker version in mercury-treated felt)
and I've shamelessly cut earflaps for it.
