Hemming and Hawing

Your opinions will most definitely be appreciated! I have been working on Vogue 9668, described on the pattern envelope as: "Lined dress, below mid-knee variations or lower calf, has neckline variations, fitted, self-lined bodice, midriff, tapered or flared skirt and back zipper. View A: short sleeves."

One day last year I ran out to buy this pattern (which is still in print). I had to have it right that moment! I was going to start it the very next day! And then it hit me that fitting the bodice would not be easy at all. It's taken a long while to work up the courage to wrestle with it. Even though this dress is far from perfect, at least it goes around me without falling off my shoulders. I started with an 8 in the upper chest and added ever-so-much width and length to the bust (and width to the waist). In fact, now I know I overdid it with the FBA, but no way am I ripping out all that piping and lining and stuff. This version will be good enough for itself.

Now I just want to hem it, review it, and move on to another version. My mom very kindly crawled around on the floor marking an even line and pinning up a hem. She even went so far as to take a photo. I wish we had gotten a front view, but I hope you get some sense of it from the side.

I'm worried that this is a touch too long and a bit more matronly than siren. I'm also worried that I need much more powerful underpinnings than those pictured, but that's another issue. My mom favors this length. What do you think?
