Revamping another floral robe à l'anglaise

First of all, I must introduce my new friend to all of you who aren't my friends on facebook. A while ago I found this nice dress dummy from a second hand store and even though she isn't exactly my size she can wear my dresses surprisingly well for a random find. I'm considering padding her at some point I but at the moment I'm feeling too lazy to do it. And I'm not yet sure if I want to do it anyhow because right now she can wear one of my friend's dresses (without stays) as well as mine (with stays).  

Currently I'm revamping yet another floral robe à l'anglaise that was made a few years ago. Basically it wasn't in desperate need of a revamp but it bothered me so much that something had to be done to it. I ended up taking it almost completely apart because it was badly machine sewn and because the lining was loose and made out of sheet so I had to cut new pieces for it from linen. At the moment the dress nearly completely reassembled, lacking only the sleeves and hooks and eyes. Eventually the skirt of the robe will be looped up with tapes on the inside of the dress. This is how it looks now:

Since this is an old gown, I'm starting to feel like it needs something new to it - to cheer it up a little bit. This is not my gown so the final decision lies in the hands of it's owner but I'd still love to hear your opinion about it. The original plan was to decorate the dress with self-fabric trim but after some research on the net I realized that none of the similar extant gowns had self-fabric trimming. Evidence can be seen on this Pinterest board. 

I know many costume makers just love to trim their dresses heavily with self-fabric and I sure love to do so as well. But now I feel like I really don't want to do it with this dress like I did with the earlier robe à l'anglaise that was already doomed to be historically inappropriate because of it's fabric. But this fabric looks much more historically appropriate so I wouldn't like to ruin it by decorating it in a way that isn't. So what do you think? Have you stumbled upon a floral robe à l'anglaise that is indeed decorated with self-fabric trim? Or any other kind of trim that I could use? Of course accessories will make the whole costume look a bit more interesting but I still feel like the robe itself needs something to it. Please let me know what you think!

And here's one more quick shot of the bodice...

This is what the gown used to look like when it was made.

I don't think I have quite enough fabric left to make a matching petticoat but I'm thinking about making either a light blue or a sheer white petticoat instead. Or maybe even both. The petticoat seen in the two old photos no longer exists.
