BUR #54613 has been approved by @evazion.
mass update favgroup:51948 -> coordinated_clothes_writing
create alias couple's_shirts -> coordinated_clothes_writing
We currently don't have a generic tag for this concept. matching_outfits is far too broad to find these posts, and while several examples exist under i'm_with_stupid_(meme) and i'm stuff (meme), both are messy and in need of cleanup (which should be a lot easier once coordinated_clothes_writing exists).
I know the proposed name sucks, but the reason I'm using it over couple's_shirts is because it's not always couples and it's not always shirts. Any other suggestions for utility aliases (or the main name) are welcome.
