Sparkle-icious has three colors, gold, blue and pink where as Mad as a hatter has several different color glitters of different sizes in it. The glitter in Sparkle-icious seems to all be the same size glitter.
Although, if you can not get Mad as a Hatter I suggest layering Sparkle-icious over a dark silver like Lucerne-tainly Look Marvelous, it appears much more the same that way.
This picture is one coat. Mad as a Hatter is on pinky and middle and Sparkle-icious in on ring and index
These pictures are three thin coats.
