I use my shapes in brackets like (Legacy), so would be #RLV/skirt (Legacy) and #RLV/Skirt (Lara). I use both Lara, LaraX, Reborn, Legacy .. so the only "mess" is setting the folders up right
That way you can even add #RLV/skirt/Long (Legacy) and #RLV/Skirt/Long (Lara) etc as the folders are named differently
The limit is the amount of bullets/tags you can show on the item.
If too long, I spilt the outfit/clothes into bodies at top level, e.g. #RLV/BrandName/ClothesName (Legacy) with subfolders for /Skirt Long, /Skirt Short etc etc
