I have the nude Declics, but I'm so afraid to get them dirty. Would some kind of spray protector help? Would it be better to get the Caracolos? The pictures that NGG has of the nude ones show the color to be really dark, though. Also, does anyone know what the sizing on the Caracolo is like, and if the white zipper breaks up the leg-lengthening effect? I'd appreciate any help, and thanks in advance!
