Essie's Beach Bum Blu is a stunning metallic aquamarine, another one of those gorgeous mermaid-y colors (which I love!) This polish always caught my eye whenever I saw it on store shelves, it really does stand out. This is a cute, fun shade and it's so vibrant. Not what I would call sophisticated, but it's not tacky or juvenile either. More like what I would wear in the summertime or for a pedi.Excellent formula, opaque in two coats. No problems with application or wear. Four lippies instead of five because it stained my nails a bit. Still love it and would buy it again.
