One or two performative responses on here, methinks. Cards on table, I would decline the pantaloons, the frilly mini and probably the smocked sleeve dress too. In fact in the highly unlikely event of my ever needing another wedding dress, I would actually want a suit like the one my great aunt wore when she got married in around 1915. (Incidentally I have never seen anyone smile in early twentieth century photos, including weddings, and I assume they all had a perfectly good time.)
But some of the other outfits look beautiful to me and not in the least outlandish. I love the shape and the severity of the dress the op has linked, although I fear for the feathers once the champagne's cracked open.
To whom it may concern, I'm age 69 3/4.
