I love this idea!
If I know I'm going to start my game in summer season, then my everyday outfit to start is a warm weather outfit, so it would be awesome to just create the outfit once then tick the boxes that would apply for that outfit, so in the case of how I play that particular everyday outfit would be tagged "Everyday" and also "Warm Weather". Then I wouldn't have to go back and try and figure out which pieces I used for Everyday when making my Warm Weather outfit.
I would also love the ability to "save" outfits, and also to copy over make-up and skin details to each outfit.
