Like minds... I also use PPT to plan capsules! I have used it for years for travel capsules. In December I started a PPT to focus on work wardrobe planning. But mine is nowhere near as pretty as yours -- I don't have the patience or the eye I guess, to crop/resize etc. And lots of the photos have models wearing the tops, since I buy so much from Ann Taylor.
Still, I find it really really useful. It helped me clarify the colors that I prefer and that work best with my wardrobe, which makes it easier for me to resist anything that won't play well and wind up an orphan. It also helped me quickly see the holes -- and that I had a lot of patterns and not enough solids.
I find it helps to get in the habit of copying and saving a picture of any item you buy, so you don't have to go searching for it later, when it may no longer be available.
I'd love to hear how others are using Evernote for this. I use Evernote as my second brain, to track orders/returns/etc, and my wardrobe wish list. But I have not been able to figure out how to resize graphics??
