Who would have thought yellow sandals would be a current trend! I think they really can make an outfit pop. Be careful on the shade of yellow you wear. The below link shows three separate outfits. If you notice Naomi Watts has a white dress on and paired with a darker, less bright shade of yellow. However, Britanny Snow has a metallic dress on and has paired with a bright yellow sandals, which look great!!!
I think a little bit of color can change the whole dynamic of an outfit! I am even liking the new trend to wear colored heels with your wedding dress.
