Hi Mo --
Interesting read! Coming over from your other thread, to me this dress is very versatile for your lifestyle, climate, and location. Seems easy to dress up or down.
The only thing that bugs me is the strap/bra situation, but that's a personal bias.
If that bugs you at all, I'd either wear a tank style half-cami* over your bra and let those straps show, or see if I could get a tailor to widen the straps with new (maybe contrasting or printed) material. The latter is a project, I know!
*I have had great, worth-the-money luck from SecondBase camis (I think they have a 15% for new customers if you ask, and they do have sales every so often). You can always try to hack off a cheap tank and see if it rolls up on ya.
