Mock-up Done, Tweaking Needed

Alright everyone, here's a mock-up of my design.  It's not perfect, so you will get a glimpse of my beige bra against a beige dress and panty lines.  I'm sorry for any offense that may be stirred.  I found this heavy knit in the discount section of JoAnn's and it's working well for the mock-up.  The color is horrid for me, the final dress will be a rich jewel tone.

I'm very happy with the concept and the seaming work went together like a dream.  I was playing around with the idea of piping the seams, so I serged the seams on the outside and then top stitched them down.  I'm thinking of just sticking with understated normal seams, letting the subtleness carry the design.  Also, less work.  The final dress will have an all-in-one facing for the armholes and neckline.

I'm too tired to smile in this picture.  I think the dress is too tight.  I'm wearing borrowed Spanx but there are wrinkles around my tummy indicating that it needs more room.  The nursing overlays are a mess, but hopefully easily fixed.

Hmm.  Odd twisting is going on here.  Also, the upper overlay isn't long enough to cup under my bust.  The lower overlay needs a dart taken out of it to cup under.  And what is up with the neckline?

This is with the upper overlay cut away from the top three seams and repositioned to take out the twisting.  Much better.  I took out the excess from center front at the neck.I still need more length to the overlay to cup the bust but it's better than before.  Here's a picture of the shoulder showing how much I need to add to the overlay.

Now for the back.

I had a lapse of awesomeness and flipped the midriff inlay.  I think it's contributing to the fit problems in the bodice.  My next step in fixing the muslin is to cut out the midriff, flip it back to its correct orientation, abut the seams and do a zig zag stitch.  I can't properly analyze the fit until that's done.  I'm not looking forward to the work.  Also, too tight in across the hips and rear.

Things I love about this:

The seaming details make me feel so feminine.
The sleeves are perfect.
And, after I hem it 1 14/" it will be the perfect length.
I patterned all the pieces correctly except the nursing overlays, and I knew that would be trial-and-error.

Alright, I'm awaiting your comments and criticisms.

Edited to add:  I've flipped the back midriff area and then pined out a 2" tuck on the back bodice at the armpit level.  It's fitting much better now, but still needs 2-3" of ease around the hips.  Or more?  Do I need more than 3"?
