Basecoat: Salon Sciences Instant Artificials (1 coat)
Color: Orly Au Champagne (3 coats)
Topcoat: China Glaze Party Hearty (1 coat)
Topcoat: Northern Lights Silver Hologram (1 coat)
Au Champagne is a pretty, shimmery opaque white. It's a little softer than a straight white. It dries to a satin finish, which I thought was interesting, but I also think that's why it applied so nicely. I had zero problems with it.
I might as well have skipped the holo topcoat altogether, because the sun has not been out - at all - until this morning, and these photos were taken yesterday with already four full days of wear (see tip wear if you embiggen).
