I chose Layla 11 to try first. It's a taupe-y mauve subtle shimmer in the same family as Essie Demure Vixen and Estee Lauder Surreal Violet. I used two coats (no topcoat).
I wasn't fortunate enough to have sunshine when I had this one on, so I can't show you the shimmer on the nail (it only comes out in really bright light), but here it is in the bottle.
Many of you probably suspected from seeing the bottle lineup that I would not stop with trying just one of my new polishes, and indeed I did not. I added one coat of Kiko 231, which the Kiko website informs me is called Multicolour Paillettes, though the bottle just says "231". I really liked this combination; the soft colors of the glitter blended so nicely with the Layla.
Thanks so much, Flavia!
