OPI nail lacquer is a quality varnish and with a retail price of £12 a bottle it isn’t cheap. If I want a super shiny finish without chipping for weeks this is the usual product that I would buy. However, I had an interview recently for a new job and I didn’t feel like OPI could quite cut it. After splurging £17.50 on a new Dior vernis I felt more powerful, fashionable and promotion worthy. Dior market this product as a ‘high lasting, haute couleur’. Despite people not being able to tell the difference between the two, it was the psychological effect of wearing the ultimate luxury polish that made me feel more confident that day.
