The closest well-tagged clothing equivalent to Renamon's armwear is bridal gauntlets, not gloves. Hence most models that use danbooru-style or e621-style tags (e.g. most anime and furry models) use the term 'bridal gauntlets' for this. Gloves cover most or all of the individual fingers, whereas bridal gauntlets cover the forearm, wrist, and sometimes part of the hand - akin to typical armor gauntlets. For models that don't have a concept of bridal gauntlets you could certainly try terms like 'fingerless gloves' or 'detached sleeves', or place 'armor' in the negative prompt.
