The pattern ideas

As I said I've been thinking about the design. I've come up with two ideas so far.
1. the singlet with skirt, grafted together, but afterwards I could take them apart again and wear them seperatly.
2. the coat, I have to show the pictures of what I mean.

Here are some sketches I've made so far:

Back and front of the "coat"
I would need to knit these sections and put them together afterwards:


I hope you can see them, they're pretty light.

The advantage is that using the lace at the back and a bit of smocking at the sides, I could control the fit quite acuratly, without changing the design. This would be nice as I do change bodyshape like all people. The disadvantage is that it would be harder to change the dress so I could wear it to any occasion and it would be just hanging in the closet most of the time, wasting away.

Perhaps I could make a combination though, have lace fitting at the back of the singlet part and just have a round skirt underneath.
