Kathie, Irina and Firecracker, thank you for the helpful comments! I know I can find Angie's sleeve-scrunching tutorial here and that will help the shape of the tunic. White jeans is a great suggestion! A bit of collar popping and even trying some small shoulder pads might be just the thing, too.
I'm headed to Nordstrom today to make my returns. There is only one Nordstrom in all of Phoenix so it's hectic even on a non-NAS day, much less a Saturday during NAS. I will be focused on my mission to get in and get out!
