I propose the use of a general "lowleg" tag for posts containing that style of clothing. I've noticed two separate tags for this: lowleg_panties and lowleg_bikini. I've also seen some posts with the lowleg style but contain neither panties nor bikini (can't recall it at the moment).
I've come across some posts using the incorrect lowleg tag, so I just think the general term would be a bit easier to tag with and still imply the same meaning. Searching for specific lowleg posts would also be easier using "lowleg" in combination with panties or bikini, for example.
