It's Jellyfish I, right? Like, Roman numeral-style? Not 1? (Personally I think the second version should have been called Jellyfish II but I suppose that is neither here nor there, as said in my nose-up tea-drinkingest-with-the-pinkie-out voice).
Jellyfish I is a white base with a deeee-lightful golden flash and tiny purple, light blue and gold glitters interspersed all up ins.
Shown below is three thin layers with Essie G2G topcoat.
It's kind of like warm sunshine on my nails, you know? I haven't looked at a jellyfish in a long time, but yeah, I'm sure they'd probably like having this polish named after them. They'd probably even wear it on their nails, if they had nails... on the ends of their tentacles... which would be horrible.
Truth time: real-life jellyfish kind of freak me out. I like the cartoon kind, though. And those moon jelly guys are pretty all right too.
