The horror that is knits - Marian Martin 9329

I never see knits, I suck at it. However when I saw the 4 yards of 60" green polyester knit at Goodwill for $1.99 I had to buy it. I have no clue how this one is going to turn out. I have been reading lately instead of sewing so this is a challenging "back to work" project. I am using the stretch zig zag setting on my machine; hopefully this will eliminate my need for any closings on the dress. I want it to be completely pull over. I am a little worried that the pockets will be too floppy.
