My favorite glitter is the pink hex layered perfectly over the black hex. (:
Cake-Hole is a Macy's exclusive Butter London color. You can purcahse it online or if you are a lucky-ducky, it will be in your Macy's beauty department.
I purchased Nostalgic As If! from Copious for $0.01!! I have purchased about 6 polishes from Copious and the most I have spent is $0.60. They frequently give out $10 credits to existing customers and you get $10 to spend when you sign up through a link. Here's my Copious link if you haven't joined yet! I've had nothing but good experiences so I recommend joining. http://copious.com/invites/4fd174a46058f159520071c0
