Hey Sailor Boy consists of blue and green hexes and small blue glitter in a dark blue base. It looks similar to the popular Deborah Lippmann Across the Universe, but they're not exact dupes of each other. HSB seems to be more dense and not as dark.
Instead of layering it, I wear it alone. This is three coats. All of them dried fairly fast. It was really easy to work with, not too thin or thick. Clean up was the hardest part because of all of the glitter.
I love Hey Sailor Boy. I really want Across the Universe, but this one is satisfying my lemming for now. If you have an Icing store near you, I definitely recommend it.
