to be fair to OP, on the style & beauty boards, regulars often give an indication of where they sit on the House of Colour spectrum - it should give a better idea than what type of job they do in terms of what suits them.
Saying that I haven't had my colours done and I am dying to know where I would fall on that spectrum 
I think the dress is classic style that would suit an hourglass, however would look more like workwear with a cardigan or jacket as its very figure-hugging.
