couture is one of the first polishes in opi's designer series collection (4th, to be exact), which means it was probably launched in 2007. so far i swatched illuminate, extravagance, fantasy, tapestry, mystery and radiance.
couture is one of those shades that is almost impossible to describe. it is pink and coral and bronze and peach at the same time. it is maybe a bit underwhelming, but a safe choice.
i remember these early holos to be thin and hard to work with, but i think i exaggerated it in my head as it was fairly regular. two coats were enough. it is not a polish i dream of wearing, but it is neutral one that can blend in.
