I don't own many OPI polishes, the ones I have I picked up from Sallys on clearance. Diva of Geneva is what I would class as an autumn colour. It isn't a shade I normally sway towards but I think that is why I like this colour so much - it isn't like anything else I own.
Two coats of Diva of Geneva and one coat of Rainbow by Gosh - a gorgeous flakie top coat which I have worn several times.
I love the look of flakies over a dark base, they look like fallen autumn leaves - irregular shapes with a copper and gold sheen.
