My reasoning for purchasing this shade is that it was in Superdrug's recent 3 for 2 offer
and I had two shades that I needed a third shade to add to the collection.
After a quick Google search I really liked the look of Essie's Mezmerised
as it looked to be a true cobalt blue and something similar too Nails Inc Baker St.

Wrong! Yes the shade looks bright and beautiful when used in flash photography
but in natural light/real life it is more navy, dull and flat than dazzling bright blue.
I'm sure many will have a need for a navy type shade in their collection
but for me it is nothing special and a shade I wish I hadn't purchased.

Formula wise it is opaque in one coat which will appeal to most of us.
I had to admit that it dries and applies like a dream -shade aside
but I do find the Essie diffusion line brushes to be a little too big for my nails
and I did make more a mess than usual but that is purely a person problem
so you may get on far better than I did!

Have you picked up any of the shades from the Essie diffusion line?

Nail Polish Disclaimer - I will no longer be commenting on the wear of nail polishes
unless it chips instantly etc as I change my nail colour too frequently (sometimes daily),
to comment properly on the wear and as we all use different techniques such as top coats/base coats
I don't feel that my comments on wear time are helpful in any way.
