I might be in the minority here but do you 'have' to wear a dress at all? Was just thinking that your brown pants outfit in #5 would look fab with the faux fur jacket & the shiny brown boots from #3. Would need to cover up the drawstring with a belt though!
Ultimately though I think the shoes will be the most important part of your outfit - so start with a pair that's comfortable then go from there. I don't think you could go wrong with any of the dresses featured here - even the green one with #3 boots would work
