Well mine has changed a bit now I have got a couple of long DV hoses and a custom LP hose for my BC inflator.  But when I first inverted I had the following.

Drysuit inflator under right arm.  

BCD inflator (Standard length) again under left arm and looped down onto inflator (It was too short to go over my shoulder and down, but under the arm worked and I could still lift the hose to dump).

Alternate (Standard octo length hose, 36" ? ).  Under left arm and necklaced around my neck.  (I found it was just about long enough, maybe just a little awkward, but you could put an elbow or swivel between the hose and 2nd stage to assist with the hose routing).

Finally 5ft (not 7ft, my preference) around the right hip up across body to left shoulder around behind my head and in my gob.  Long hose was always wrapped last so it sits on top of any other hoses, so if you do donate it does not get caught up.

Slight changes since,  4ft hose on alternate so I can bring it up over my left shoulder and necklaced (or behind my head and in on the right side) I use 2x sidebreathers so it will not matter which side I bring it in).  Drysuit in under left arm now.  Custom LP hose off right hand post up side of cylinder behind neck and down to LP inflator.
5ft primary Long hose as before.

If you get one long hose you can probably make do with the rest of the hoses, you might need an elbow on the alternate though just for comfort.

FWIW,  I still use the 5ft long hose with singles on holiday and standard hoses for everything else.

I might see if I can draw it out but I am by no means an artist (Well not that type).
