Is there a reason we have a school girl tag? Is there anything that tag gains us we don't get with school uniform? The tag has no wiki but >400 posts, so I wouldn't want to purge it if there is a reason to keep it. As far as I can tell though, an alias to school uniform would probably be appropriate.
EDIT: Apparently schoolgirl is already aliased to school uniform, so that's a pretty strong precedent.
