Oh, man, ladies!
I've always wondered what my actual wardrob size is - that's part of what began me on my path of keeping my spreadsheets two years ago, actually, since I began it to try to get a full inventory!
Now that you are all talking about >333, I got curious if I would be able to take part, and started playing with my unique items data set.
I haven't documented every day - days I'm camping, for example, or lounging around the house or ill, I don't track outfits on, bceause "20 eyar old t-shirt and college sweatpants" doesn't seem worth it. LOL! BUT, there are days that I changed to go to dinner or similar, and I have tracked that.
I document bottoms (skirts, pants, jeans, dresses all go in this column), tops, toppers (jackets, cardigans, et cetera), and shoes. I have what I call a "running wear" tab that I use to fiddle with the data - in that tab, I keep two main bits of data: one of all wears, so I can see how many times I've worn an item, and with what; one in which all duplicates are removed, so I can monitor how many unique items I've actually worn in total.
At any rate, I just went in and removed all the days that I didn't track (I document them as "no info" or "camping" or whatever, because I'm... Well, I'm a nerd at heart). Then I totted up the unique items bits totals. Even knowing I have a robust wardrobe, I am shocked to find 407 items have been worn by me this year; 101 of those items alone were shoes.
Yep, it's time to do some serious reviewing.
