These Newport News sandals named Strappy are a great wedge for spring. Make a go-for-it, and try these with a kelly green skirt.  Something with tucks, like the one shown. For your top try a plain light green tank top and tuck it into the skirt. Wear a necklace that has a grey tone to it, like the grey from the sandals.  Find one that has an interesting detail. It will pop off the green so well and give your outfit the attention it deserves. The Urban Outfitters necklace is $58.
