Thank you all--white cami it is!
Angie--yes, the topper situation is still dire. I do not have one that will contribute to the outfit in a positive way. Probably, I will wear a black, fitted, field jacket--it's nice but it's too big on me now and relegated to "gear". And black isn't my first choice. I also have this one (finds) in blue that I recently bought as a placeholder, but I don't fancy it with the cuffed jeans.
ETA: Or, of course, the matchy-matchy denim tuxedo look--which might be the best option here, although not ideally my first choice.
