Porchester Square has to be the most popular shade from Nails, Inc. Even with all the gorgeous colors Nails, Inc has to offer, Porchester Square always comes to mind when I think of their polish.
Nails, Inc. Porchester Square ($9.50) is a greyish nail polish with slight purple undertones. The color seems to change depending on the light, leaning more to the grey or more to the purple side. This shade screams "cozy fall sweater!" to me for some reason. I only like to wear it in the fall as I find it a perfect shade for this time.
Although pretty on its own, I wanted to jazz the mani up a bit and bring in some color. I used Petite Pink Diamond as my accent nail.
Formula wise, the coverage of Porchester Square is great, and lasts a long time on the nails. It is not too runny or too sticky, it is the perfect consistency and is easy to work with.
