OMG perfect timing as i literally was just about to rec this app. i’ve had it for a while and it’s really useful. it’s like $5 and totally worth the investment.
there’s options to upload your entire closet (by category), and then make the items with transparent backgrounds so you can build outfits, which you can then save and even add to a calendar. you can also tag each item with color/fabric/size/etc
there’s also a “packing“ tool that lets you plan outfits and creates a packing list. i don’t use these features, but there’s also a shopping tool, style guides, and “style stats” (of your wardrobe). it’s no-frills either, so super easy to navigate
