BUR #10327 has been rejected.
mass update partially_unbuttoned -unbuttoned -> unbuttoned
mass update partially_unzipped -unzipped -> unzipped
create alias partially_unbuttoned -> partially_open_clothes
create alias partially_unzipped -> partially_open_clothes
The main point of these tags seems to be that the clothes are partially open, not whether they use a zipper or buttons. Separating the two based on this arbitrary difference doesn't make much sense to me, especially when you could just add unbuttoned or unzipped (or both) to a partially_open_clothes search for the same effect.
This idea was previously floated in topic #19639, but nothing came of it.
