I used to work for a management consulting company, so I dressed differently - business casual, probably a lot of things from Banana Republic. My wardrobe now is definitely more expensive, but I always dress for the occasion.
But I now think what I was doing, in a completely unconscious way, was getting off the turf where my husband and I might be rivals. We were both working in fiction... so I look back and I see that I consciously vacated the contested ground.
