I track wardrobe details across 28 types (shirts, slacks, footwear, etc.). Even with just 2 items in each wardrobe category, that would give me over 268 million outfit combinations. So, the size of my wardrobe is not as big as some on this forum. It's just a matter of getting it all into a database where the number insanity can be calculated. The numbers below are for fun but are limited to business outfits only. No shorts, casual shoes, short socks, etc. With that limitation, I can make just over 28.5 septillion outfits. If I wanted to wear each of these in my lifetime, here's what it would mean!
