Do you care if you match or clash with your s/o when you go out? My family thinks it's hysterical but if we are about to leave the house and I notice we are clashing or (worse) wearing the same color, I will frequently suggest one of us change. This is also true if the whole family is going out together. It really bugs me if three of us are wearing stripes, for example.

If we are really dressing up for an occasion, I will make an effort to coordinate our outfits/colors....just in case we end up in a photo

Here's another related quirk: If you and your spouse both have leather jackets, do you wear them at the same time? The same color leather?

Am I nuts, or do you guys get it??
