Illamasqua Phallic is quite an interesting color. The company describes it as a shimmering midnight navy, which is pretty darn accurate. I haven't seen a bottle of Essie "Starry Night" in person, but this is what I'd imagine it would look like. Illamasqua's website shows Phallic to be lighter than it is - it's definitely a DARK color. I'm calling this a glitter since it has glitter in it - more so than a shimmer. The polish was very easy to take off as well. I wore it overnight and didn't have a problem with color bleed on my cuticles when I was removing it.
The squared off bottle is a little hard to work with but I preferred it to the actual brush top, after I removed the square top.
I used Seche Retain as my base coat (trying to keep my nails strong!), 2 coats of Phallic to cover all bald spots, and a top coat of Seche Vite. The formula on this polish was quite nice - I didn't have any pooling into the cuticles and but it wasn't too thin either.
Shade pictures just wouldn't work here, so instead I have 2 sun pictures for you.
This one shows you more of the blue in the bottle - while this picture is color accurate for the blue, it's definitely not what you see mostly on your nails.
This is more like it. Very dark dark navy with a hint of blue glitter. It's still very pretty but not a good spring color by any means. ^_^ I'm interested in trying more of this line - the application was very nice.
For those in the States, you can purchase Illamasqua from Sephora [official website] for $14 a bottle.
