Outfit Post and Modesty Recommendation: Date night

I've been on vacation all week - vacation at home, that is. So I haven't gotten around to posting. Tonight, however, I'm going out on a date with my husband and thought I would post this outfit to show what I do to make a halter dress modest (to my standards). Last time I wore this dress, I wore it like this. But this time, I decided to try something different. This dress (like most halter style dresses) is cut very low, but being it's 90 degrees outside, I didn't really want to add the extra layer of a shirt underneath. Instead I just added the scarf. I think it covers nicely without taking anything away from the dress.
