Maybe I'm a pragmatist but unless I'm going to be able to get several uses out of a garment per year I won't bother purchasing one. I'll hire one.

Then again, due to the climate in my region, black tie events are usually reserved for winter. White tie events are literally non-existent, even among the upper class (middle class to the folks across the pond).

Darn it, though, those satin shawl lapels are fabulous! Now THAT is an Argyl jacket!
