Bug or Fashion design?

The Gloves of the Black Griffon https://na.finalfantasyxiv.com/lodes...em/41f36e70050 do not override/cover the sleeves of the Robe of the Black Griffon https://ffxiv.gamerescape.com/wiki/R..._Black_Griffin.

I am not sure if this intentional or not, so I didn't want to post in the Bugs forum. Also, anyone know of anything that can be used to cover those huge sleeves?

There are a few robes and coats that override gloves regardless of their length. The Expeditioner's Coat and Orthodox mage robes are two others I can think of.
