Re:Do you own Formal wear?
I'm on my 4th or 5th tux with two different style jackets (a knotch lapel and a shawl lapel) I also have a white jacket (Shawl lapel), and tails (Peak Lapel). I have two white vests, 2 black vests and a special white half-vest (no back) for my tails. I have bow ties in Red (2), Black(3), Green, White(2), Magenta, Plaid, powder blue, and a few others, all have matching cumberbunds (although I rarely, if ever, wear those any more!).
I wear some assortment of tux apparel at least once a month - usually the regular black tux, with white vest and white bow tie, if not more. Maybe 20 times per year. In the summer months (Memorial to Labor Day) I wear my white jacket in place of the black. My tails get used about once per year.
However, I NEVER wear a tux when going out to eat, or a play, or classical concert. And I can't recall the last black-tie event I went to. If I went to the opera, I would wear my black shawl lapelled tux.
