The herb looking off hands are fairly unobtrusive.
There are many tiny mogs for that.
I agree Invisible offhands pkz!
Yes, of course it should be hideable. But I think there are so many transmog options for offhand that you won’t having a hard time finding a good one. On my monk I use a fan for example.
However I don’t get why we don’t have the option to hide every item (including pants… especially if you are wearing a dress on top of it… and especially since you can unequip it and walk around naked with no problem.)
Also… /waggle
Also… make draenei underwear jewellery match the jewellery on the head and tail.
I believe “hide off-hand” should be available, as well as the option to “sheathe on back” for any 1 handed weapon in the game. I don’t think weapons look good dangling from the side at all.
Update: There is an off-hand in Dragonflight, that, as of today, stays invisible as long as you keep it sheathed. It is a crafted off-hand called “Core Explorer’s Compendium.” Hooray!
Just use a book offhand tbh. That what I do when I don’t want anything on my right hip.
