I do wear those off white RAF gloves when flying, mostly for taxi, take off, approach and landing. The reason is that I had to wear gloves in my air force flying life, and it became second nature.
But it appeared to be very useful in Big Lady computerized ops: As you might know, those super automatic thingies works pretty fine on their own, as long as everything works fine precisely, and then there is absolutely nothing to do; in this case, wearing gloves prevents me to put my fingers in my nose, or indulge in even more frowned upon practices.
However when something goes wrong in the system(s), there are hands all over the place in (what really becomes) the cockpit, and wearing white gloves helps me seeing where MY hands are at all time.
