Hi Carter. I have similar spreadsheets. They are literally my most useful wardrobe planning tool.
From what I can see of your spreadsheet, you track category, number of items in each category, and colors. All very useful information.
First, you know what categories of clothing you love and wear. For example, you love pants, much more than dresses. My first question for myself would be, are these realistic quantities for me and my lifestyle? Do I really not need or wear dresses that often? So that information informs future buying decisions.
Second, I look at the numbers. For example, I love to wear lounge pants to wear after work. I own exactly ten pair of lounge pants. I came to realize that "ten" was the magic number for me. I don't need any more. I can't possibly wear any more than I currently own. Hence, I am no longer shopping for lounge pants. This was very useful information, because I used to swing through the lounge section every single time I went to the mall. Every single time. Now I have numbers that show I can direct those monies toward other purchases. In my case, tops.
Third, based on the numbers, is there a category in your life that needs to be amped up? Do all the quantities feel "appropriate" for our life style? Do you have "enough" in each category to be satisfied? Do you need to shop other categories because the numbers are sparse? I personally have always been "bottom heavy" and "top poor." That directed my shopping strategy.
Finally, I start to evaluate the color schemes. Your color scheme looks very coherent. So I can't really say much here.
Great job. So sorry about the water damage. Has it been fixed? Water damage is one of my biggest fears in life because I have seen what it can do and it shocks the senses.
