I tried to search but could not find a thing about this. Anyone know where I might be able to get a set of grey robes with a hood or monk robes with hood? I want bigger robes for my mage and less tight looking. Anything similar to the grey beards but with just plain looking robes?

are you on pc?

if you on pc type grey help 0, if there are greybeards robes, or grey robes it will be there on the list.

there's a tailor in Solitude that sells a wide variety of clothing. Monk's Robes are among them.

Can't find a picture per say but this link had some you could get if on the PC. I saw some in the book about the darkbroother hood quest in a little picture on some guy to kill later when doing the quests from the night mother and thought there might be more out there. They look the same as the grey beards but all gery and plain: http://www.skyrimnexus.com/downloads/file.php?id=1047

I tried the radiment place in solitude and the monk robes look like blue robes but only tan.

In a random wardrobe or dresser somewhere once I found something called Grey Robes. They don't look like the Greybeard ones though, but if on PC you can probably use the console to get some (I never tried, so I don't know if it works for these, but I do know that for some wardrobe items, there is a code but it won't give you the item for some reason).

The name of the store is the Radiant Raiment.
