With that pattern, I vote for neck line, cuffs, and hem of a sexy over tunic(s), with the pattern enhanced through the addition of embroidery, beads, jewels, or something...

or it might just plain make a tunic in and of itself, but it screams establishment, rather than background, to me.

And if you can't decide, I'd be more than happy to take it from you and show you what I mean on a tunic to fit me. ;-)
