one of my rare 2017 purchases (for now) is actually an ancient picture polish shade, sky, from their light shades collection in 2007.
it is a really special light blue pastel, really resembles the sky but in its a bit murkier mood. the formula is nice, especially for an old pastel, but it needs three coats. nevertheless, they run smoothly so i don't see it as a bother.
i wore base coat (china glaze strong adhesion) + three coats of polish + top coat (essence btgnts)
