I've picked a name for the pattern. As nice as "Diamond Brocade Top" is, it's not really a pattern name. So, having finished the test knit in the proper yarn, I've named the sweater "1989".
It's got a really fun 80's vibe to it, without being overtly 80's. I'd recommend it with tight jeans and high boots. You might even find me wearing legwarmers with it (I love leg warmers and never have enough reason to wear them).
I'm wondering if I should play up the 80's hair a bit for the pattern photos? My hair doesn't really do 1980-anything very well. Except bangs. I do bangs very well.
