The order of the colors will go by the order you choose them for example if you choose the colors in this order light grey light blue light green white that is how the outfit will be. Of course if you want the outfit to be 3, 2 or 1 color just choose the colors in the order you wish them to be for example you want the outfit to be only two color then you will need to choose the same 2 colors for all 4 options and remember to put them in the order you wish them to be in.
 
PLEASE NOTE:the sizes goes by what the child wear not by age since this is crochet clothing. For example the baby is 6 months but wears 0-3 in clothing then you will need to get the size 0-3.
