if you don't want too many different colors, then choose those from the same family. Eg. pink cardi with red bbag (or vice versa) or turquoise cardi with emerald bbag (I think a emerald first would be nice) ..... hmmm.... personally I wouldn't do sandstone, it's a very earthy color and I think it'd "drag" down the gorgeous colors of your dress, JMHO. Show us pics when you've decided!!
