We have a lot of these
-people know we spend very little on groceries, but aren't aware that my kitchen it packed with high end cookware and tools, it's a chef's paradise in there: Staub, Le Crueset, Japanese knives, copper pots, the big Cuisinart, etc, etc
-Like pp above suggested, we both have a full on suite of health care: massage, physio, therapy, Invisalign, orthotics, Lasik, etc
-Also.like pp above suggested, I have a top of the line team of lawyers, accountant, consultants, and financial professionals to handle my business affairs when needed. A deal recently fell through that would have cost me at least 35K in fees for just the first step.
-We dress very casually, however, each piece is merino wool, mostly from Ice Breaker, and cost approx $200 each. So although we're sitting around in t-shirts, lounge pants, and hoodies, we're each wearing close to $1000 in clothing to look vaguely unemployed.
-Outerwear. We live in a part of Canada with a wild range of weather. There's no $1000 designer coat to be found, but there are several thousands of dollars of technical layers to cover every possible weather situation and keep us comfortable outside. There's no such thing as bad weather, just the wrong clothes, but having the right clothes for all weather conditions is expensive.
-I don't wear makeup and my hair is almost a buzz cut, but I get regular Botox and use high quality skincare products. People think I'm less vain now that I don't wear full makeup daily or have fussy hair anymore, but in truth I'm still vain, just less insecure about how I look without all the war paint.
-My cats. They themselves are expensive (a Rex and a Sphynx), and they have top of the line everything including a Litter Robot and Surefeed chip activated food bowls. Their food is more expensive than ours.
We both look super young, to the point that we both get carded semi regularly despite closing in on 40 and 50, we dress like we're in university, and we live in a building filled with students. So basically, we spend a lot to look like two broke kids with a couple weird cats.
