Who wants to help me think outloud?

I'm making some progress on my sheer 1860s bodice. The mock-up/lining fit great, just needed to take in a dart on either side. so now I have to figure out my construction method. But when I try to talk to Momo about it he just blinks at me and picks up another piece of hay. I know he's trying to pretend to be interested, but it's really not his thing.

A remind of what we're going for. or this one

I'm really hoping I have enough fabric for pagoda sleeves though.

( So if anyone would like to help me think this one out... )
