Yes I need her to represent a character in my upcoming graphic story. Does such a figure/character exist? Thanks for any help.

Alyson 2, JessiHiRes, Roxie, Lefemme, Lafemme2 with bodyFX morphs, and Dawn with the Base morphs all have breast size morphs. Some dials are in the body and some are in the chest.

As far as super long hair, define super long. Are we talking waist length, knee length, ankles, dragging on the floor?

Yes dropping to the floor because she uses it for modesty no slotting! Is that kinky?

As already mentioned, there are many different figures that have breast size morphs.

The challenge with your request will be finding hair that is floor length.  Conforming hair, or prop hair made with geometry, won't fit the bill for two reasons. One, you'd probably more than likely need to create a morph that makes the hair that long, which will distort the textures. Secondly, lengthening the hair will not make it work as designed because the longer polygons will be stretched out beyond what they were designed to do.

Your only option will be to use dynamic strand-based hair, and I'm not sure that there is one already that is floor length for ANY character. So you're more than likely looking at creating or purchasing a custom-made hair. I might be wrong.

Some super long hairs I am aware of and I own (all of these come with adjustable length and have adjustment morphs to fit onto different figures--note they are all originally were made to fit Victoria4)

I don't know that it would be possible for dynamic hair. I just tried to lengthen my very long hair and it would only go to mid-calf length. I haven't draped it yet so I don't know if that would be prohibitive since I'd need to increase the vertices.

Yeah I figured the same thing.  It would need more verticies to sim properly.

The hairs that Rhia suggested might work well to cover the breasts, but for the more ... um ... private area she may need to wear a thong or bikini bottom.

Quick and dirty, using Semiramis hair and one of my custom morphed figures:

Well I'll be darned LOL

And this is Nykta hair which actually has included morphs for just what OP would like to cover breast and groin area, such as (again, quick and dirty render):

Yeah they aren't floor length but they do work for the modesty intent!

Yay thank you!🙏

This is beautiful hair.  T to cover the entire body fr ont a nd back (weird story describes it thusly). Could I use two or three of them to accomplish that?

Kelp hair by Arki

is very long (and free!) and can be twisted to do the modesty thing. The colour options are limited, though, because it is ment to look like a mermaid's hair. Might need some postwork in the breast area to make the hair denser.

It's rather old and made for V4.

There is a colour expansion pack:

Thanks for the tip. I’ll give it a try!
