First off, I did none of the work to bring this awesome mod, I only saved it in the creation kit for SSE.  The original mod is here:
https://www.nexusmods.com/skyrim/mods/64473/?
I didn't see any permission issues as there were no permission notes so I'm assuming this is safe to upload but if I'm wrong, please correct me and I will gladly take this mod down :)

Now on how to get this to work...
Obviously this requires Vilja SSE and Chaconne Follower to work.  A new start is required from what I've tested.  If you don't, you will get a neck seam (at least I did).  Also, I'm sure the meshes of Chaconne need to be updated but I'm not gonna upload them because a quick google search will tell you how to do it, plus there's quite a few options on Chaconne's page and I don't feel like messing with it lol.  I didn't update them in my game and everything appears to be fine on my end.  Now, download your choice of Chaconne Follower here:

...then install via NNM or your mod manager of choice.  Next, install "my" mod.  Then uncheck/disable the Chaconne.esp in your load order as all you need is the resources.  That's it, good to go
