Do you or your SO own a tuxedo?

I was just at the wedding of a relative. The invitation specified black tie. My brother explained to me that this means tuxedo, if possible, or a dark suit. He has a tuxedo and has been to a number of black tie weddings. This was my first. I have never worn a tuxedo and I have not worn a suit in ages. I was lucky to find one in the closet that still fits. At the wedding, quite a few of the men wore tuxedos.

I heard on the radio that the trend is toward more casual weddings. Do you own a tuxedo? How often do you get to wear it?
