The colour of courage: Kate Middleton looks perfect in purple at Wimbledon as Centre Court rises in moving show of support, writes LIZ JONES

Well, I'm in tears. Making only her second public appearance since her cancer diagnosis, the Princess of Wales received a standing ovation as she took her seat at Wimbledon for the men's singles final. 

And it was just so touching to see she'd brought her daughter Charlotte (a Mini Me in polka dots by Guess Girls, £70, with white ballet flats) and sister Pippa (in Beulah floral print, with an Emmy London clutch) as conker-haired moral support.

But Kate also had another very important piece of armour: her impeccable sense of style. 

The lilac midi dress with twisted bodice, the Cecilia, by London-based, demi-couture label Safiyaa (£1,295, it has just sold out!), was a winner in so many ways.

The bodice (adorned by the purple and green bow brooch of the All England club, of which Kate is patron) gave a new softness, a new ease to the princess's silhouette, which in the past has been way too nipped in.

Her hair, more caramel than of late, was worn loose and natural for Sunday's men's final

(Kate will have been mindful of choosing anything too light, due to the wind that has plagued the competition). 

The colour purple is deeply royal, but also denotes courage. 

Something the princess evidently has in spades.

The choice of nude bag by, you guessed it, LK Bennett, proves the princess is nothing if not loyal. (The Milly, £225 is sold out. I imagine the British fashion industry, the second biggest employer of women in the UK, is breathing a sigh of relief that Kate is back).

The slingbacks, by Camilla Elphick, were summery, not showy offy. Her hair, more caramel than of late, was loose and natural. 

The Halcyon Days torque bracelet and gold bangle? Discreet and classy. 

The whole outfit simply oozed, 'I am here to have fun'. 

Even the Ray-Bans, perhaps a cheeky nod to old friend Tom Cruise, inches away in the stands.

 Regal, graceful, gorgeous, playful.

Most importantly, Kate looked happy and healthy.

She finally seems at ease in her own skin: perhaps a cancer diagnosis has put everything into perspective. 

Kate, effortlessly A-list. She smashed it!
