Devialet
French for something you can buy inexpensively and ubiquoisly but since you have a keen sense of taste, obsession or a spending problem, you go for the most expensive and impractical option.
Rue to Réa while shopping in Paris: you know you can get the €126 silver panties right? You don't have to devialet and get the €2,990 gold encrusted phantom panties..... either will cover your arse.
