OP, I like your new choice. Did you go for the dark version, just to be non-bridal?
pretty in a mid 90s grunge type way - Yeah. I couldn't thing why all those nearly-dresses looked so familiar, then remembered I wore them in the 90s! I had some from Fenn, Wright & Manson. Because, weirdly, if you're wearing a relaxed sliver of a garment, fiendishly expensive fabric & manufacture save it from looking cheap.
I've just bought something similar in cotton jersey from Dotty P's. I'm so well-upholstered now, nothing looks like a relaxed sliver on me 
Show us a photo of you in your new frock when it arrives, Jan. G'wan!
