Cake Red Velvet Sewalong

Next month I'll be participating in the Cake Red Velvet Sewalong. I'm moderately excited for this dress, since, although it's simple, it has a very similar silhouette to my two favorite (and most comfortable) dresses.

I also just bought some ITY jersey from fabric.com (that I can't link to, because I bought the last of it). I've been experimenting with different knits, and I think ITY may be the answer to my question of what the knits are that look a little dressier, that are often used in rtw. (You know, the ones with a little bit of sheen to them, without being shiny.) Since there was so little left in this particular fabric, and it was on sale, I didn't bother requesting a swatch. If it doesn't for some reason, seem like a good fit for the Red Velvet, I'm sure I can find a use for it.
