Well, thank you for your faith in me!
IMO the edt is probably the easiest to wear for a man, followed by the parfum and edp last. The edp is the prettiest and most obviously floral formulation and is the one leaning most towards typically feminine. But even though the edp may be the most feminine, it's actually still pretty much unisex. There's a certain starchy freshness to No 19 that keeps it in neutral territory, so to speak.
Btw, have you tested Sisley's Eau de Campagne? If not, I recommend it.
