Dresses

I've been taking Modern Jive dance classes for nearly a year now and thought it was about time I ditched the jeans that I usually wear for it, and started looking a bit more feminine.
With this in mind I've been rifling through my wardrobe and found this maxi dress

  

It's quite shapeless so I took it in at the sides and shortened it.
With the leftover fabric I cut a couple of eye-shaped pieces, and sewed them into the armholes to make floaty sleeves, and now it looks like this

Now, dear reader, I'm in need of a bit of help.
Do you remember this vintage Central Park fabric I got from the charity shop?

Well, I've been looking for a suitable dress pattern and I haven't had any luck.
Vintage Vixen suggested I make a maxi skirt from it, and that really would be ideal - and simple to make.  The thing is, I've got my heart set on a knee length dress!
The first thing to spring to mind is a 50s style, but in order not lose any of the pattern it would end up far too long.
My next option is a shift style.  When I hold the fabric up in front of me it just reaches from my knees to nearly my shoulders, so I would probably have to add a bit more of the plain bit as a yolk.  That would not be a problem even if the pattern didn't have a yolk.  
I've got a few shift style patterns but they have curved hemlines, and I need it straight so as not to spoil the pattern.

Has anyone seen a pattern that would work?
