I don't know how you spent your weekend but I was attending a wedding at St Jean Cap Ferrat on the french riviera.
I sported white sneakers with my tux. Apparently a "very unexpected combination" according to some of the more traditional, and seriously wealthy, WASPS attending the event. To hell with them, I rocked.
(Even though, I did feel somewhat "malplaceé" in the surroundings, but that has nothing to do with sneakers, more with annual income)
