Well, this one was less of a realistic dupe attempt, actually. Mostly I was looking at that vintage Wet n Wild again, admiring the color, and wishing it had a different finish. So I made it jelly and added a few drops of grey and some Glass Slipper just for the heck of it.
Sally Girl clear - fill one quarter of a mini bottle
Vintage WnW blue pearl-frost - fill one quarter of a mini bottle
Sally Hansen Glass Slipper - fill approximately one sixth of a mini bottle
Sinful Colors Cool Gray - 10 drops
Again, the Glass Slipper is hardly noticeable. Eh, oh well. Still cute.
