The tag alias #78164 half-shirt -> crop_top has been approved.
Reason: half-shirt seems to be a redundant tag. Its wiki entry says to refer to crop_top instead, and most of the entries with the tag look to be crop tops. For shirts that are raised to half height by an external force, there are raised_shirt or shirt_lift.
EDIT: The tag alias half-shirt -> crop_top (forum #458457) has been approved by @spe.
