Bibbitty Bobbitty Boo Blue is described by Lynnderella as "glitter in all shades of blue: turquoise, navy, royal, periwinkle along with blue-violet and violet. Squares, hexagons and micro-glitter in a luscious cornflower blue base". I'm sure you could get this opaque on it's own if you wanted to, but removing that frightened me so I layered it. I used 1 coat of Bibbitty Bobbitty Boo Blue over Revlon Royal for the photos below.
I'm not huge fan of how this looked in the sun but I figure some of you would like to see how it looks anyway :)
As far as availability goes, these are a bit hard to come by. Lynnderella has a blog here that she sells her polishes on every once in a while. It's only open for a very short amount of time and those times are few and far between. I know she is supposed have her polishes up for sale again soon but I'm not sure exactly when that will be. You can also buy Lynnderella polishes on Llarowe but they are all sold out right now and apparently it's going to be a while before she re-stocks also :(
