That's supposed to be her standard outfit. Maybe it looks relatively simple because it is so dark, almost uniformly black? Also, a good part of her outfit is obscured here. Personally, I feel that it has a good level of sophistication to it. The only thing I would have liked to add is a certain kind of hood or very wide-brimmed hat. We just haven't found one so far that looks good *and* functions properly. We are using the newest generation of character model, and there aren't that many assets out there for it yet, compared to the previous generation, but that is slowly changing.
The issue with the outfit isn't in its color or textures but its design - it is very loose and looks like a bath- or a night robe loosely wrapped around her naked body, like she just woke up and threw it on herself with little care. The same can be said about her hair - it's not messy, but it's a very simple design. I might be wrong, but to me it looks like you guys have been trying to recreate the Balsamique design for her:
which is understandable (it's a great design), but as you can see, his design, while having a similar general look, definitely looks more sophisticated and formal, due to it being tight-fitted, having golden ornamentation etc. The hood definitely helps as well.
The thing with mommy Helen is that she's both a lady of the court and a high-ranking sorta nun (of a pseudo-religious order that dedicates itself to intrigues and whoring around in the name of power), which calls for her formal dress (and hairstyle) to convey her powerful status. Balsamique's design and designs in all screen adaptations do show that, IMHO:
This bitch is bad news and she should look the part - which should make defeating her plans and fucking her all the more sweet for Paul and the player. I would say that your AI rendition of her did fit this consideration better than the DAZ one.
With all that in mind I'd propose for you guys to use her current dress/hair combo as her informal dress, and to make another combo for formal occasions.
The hair should look carefully styled (with the help of some maids), like in her default look:
A hood or a hat would certainly help. May be some long cape on her back, combined with the hood.
The gloves she currently wears look fitting and should stay, IMHO.
As for the dress itself,

looks almost ideal:
But with a big "if" - if you guys can enlarge the cleavage so much that it would be clear that under that cape her tits are bare. Ideally that cleavage should go down to her pubic area, like in Balsamique design. Here's a crude mockup:
Unfortunately I have no idea if that is possible in DAZ. May be it can be set as a 100% transparency area of the texture?
