Not only do Kate Middletonand Kim Sears share a love of tennis but they've also got the same taste in fashion. White lace? Tick. Big hair? Tick.
The Duchess of Cambridge made an appearance on Centre Court at Wimbledon yesterday for the men's quarter-finals, watching Andy Murray crash out of the quarter finals losing 6-1, 7-6, 6-2 to 23-year-old Bulgarian Grigor Dimitrov.
As ever, Kate looked immaculate in a white cut-out summer dress she first wore during her royal tour of New Zealand and Australia, teamed with a straw clutch bag and a red pashmina. The fresh white lace dress is by Australian designer Zimmermann.
This was exactly the same look that Kim opted for on Centre Court during day one of the Championships, though she customised her crochet dress with a pink skinny belt, dusty pink blazer and tote handbag.
It's not just the dresses either, it's the hair. Both Kate and Kim have beautiful hair - unbelievably glossy and voluminous - the kind of hair that never goes unnoticed and makes you feel badly about your own untamed tresses.
The question is, are they friends? Do they shop together and offer styling pointers for working the Wimbledon circuit?
The style resemblance is uncanny and clearly these ladies have a lot in common, not least the love of a good blow dry.

There's a reason why everything she wears sells out in an instant, the 'Kate effect' is a real thing. (We're just not sure about the beige shoes!)
