A flurry of stars made their way to Monte Carlo over the weekend, where (we have been reliably informed) the Monaco Grand Prix has been taking place.
And we couldn't help but notice that a very definite trend was establishing itself as the look a la mode.
From Nicole's Scherzinger's chic daywear, to Jennifer Lawrence's elegant eveningwear, and Princess Charlene's stylish-but-formal fashions - it's all been about one very strict colour scheme: Monochrome in Monaco.
See what we mean?
