The fashion categories in the wiki are based on data from Lucy. Unfortunately that data isn't perfect because it's based on live, and live has more items than here. If, for instance, live introduced a second version of a classic item with a different fashion category, it's possible that my script could have accidentally picked up the live version of the item instead of the classic one.
So far however such errors have been pretty rare, and aside from them the Lucy data has been perfectly accurate. Therefore, while it's possible that there could be more items that belong in the Ringmail/Scale categories, the odds are pretty good that what's listed in the wiki is all there is ...
... or at least all there is with those exact looks. There might be other, similar but somewhat different, fashion styles on other items. For instance, the "
Plate" category of items might have a close enough look.
