What? It's been a pretty big month for weddings, dresses and rings. Last night Cat flaunted her sparkly engagement bling, after marrying funny man Patrick Kielty last month. The diamond did all the talking, but she added extra sparkle in a sequin, floral print dress paired with black suede boots.
Where? Matthew Williamson 15th Anniversary VIP Film Screening With Swarovski at Nobu Berkeley.
Verdict? This classic style has just enough bling and size wise, Cat's kept things real (there's none of this over flashy, statement-making going on).
