OOTD Challange: How to Wear Optical White?

I have this little white dress by Calypso that I thought would be a great summer staple when I bought it (in the cold winter I must say) but as a matter of fact I never wear. Why? Well, because it's too...white.
So yesterday I thought that I would give it another try and wear it to a playdate, leveraging on that little bit of tan that's left.
It seems that it's never the right moment to wear this dress. For starters, it's silk, and not a breezy habotai silk, but a pretty heavy Dupioni silk, the kind of silk that makes you sweat. I have it in another color also (a berry color) and even if it's easier to wear, I never go out in it on a hot summer day because I immediately get the sweat stains under the underarms. With the white this isn't an issue at least but there are other issues.

Total white is a difficult look to pull off and this dress is whiter than white. It's almost fluorescent white, due to the shine of the fabric. Plus, I always feel like a little communicant when I wear it, probably because the style of the dress is very chaste. And needless to say, you need to be tanned to wear this kind of white.
So the only way to wear it is to accessorize it so as to break the total white scheme and the communicant feeling. But accessorizing a white dress is no easy task.
Your only allies are necklaces and belts (a cardigan is not even an option in 100 degrees heat).
I have a few colored necklaces and probably a turquoise or coral one would work better. Anyway here is what I have and tried to play down the white of the dress.

First option, the paisley blue necklace from summer 08:



It's a little bit "Greek parade", what do you think?

Second option, with the bubble necklace in soft violet:



I like it (even if the contrast is subtle) but the bubble necklace is too high maintenance for my day lifestyle (God forbid that my daughter or one of my daughter's friends pull on it).

Third option, with a Loft necklace that is technically silver but I thought would work because long enough:



The truth is, this dress looks better when belted, so I belted the last outfit:



But less is more, isn't it:



Another belting option, but more for the evening or cocktail hour, is this Zara elastic belt with faux-rhinestones:



And with a Calypso sash belt that I had bought to wear with the other dress. I don't like this color with the white but I am kicking myself for not buying it in more colors, like turquoise of pacific blue (they were kind of cheap at $30):



And this is how I wore it yesterday to the playdate at my friend's house. I kept it simple but fresh for a hot summer day:



What's your favorite option? Do you wear total white? Do you have an optical white dress? What do you wear it with? Any suggestions?
