Full disclosure: I bought this particular dress to layer over this brown turtleneck because the colors just happened to be the perfect match for each other. But, that doesn't change my opinion on giving dresses extra wear by layering them over jeans. I'm all for making the most of wears, especially when it comes to dresses and jeans. Tip: I recommend you start with wrap dresses, you can loosen to tighten to your desired fit over your jeans. For instance you can go a little looser with high waisted jeans and give your dress a little mid-tuck or you can have it more fitted with mid-rise styles to avoid showing the midriff. I also love treating my dress like a little kimono like in this instance where I threw it over my turtleneck and jeans and paired with white boots.
