ALL eyes have been on Birmingham this week as the Tory Party Conference hit town and, while Boris Johnson seems to have been the star attraction, my attention turned to someone considerably more sartorially appealing.

I speak of course of the lovely Samantha Cameron. While regular readers may recall Mrs C and I have had our differences this year (I still can’t quite shake the image of that hideous 1970s bridesmaid-style dress she wore to the state dinner in the White House), I am generally impressed by the fashion choices of our de facto First Lady.

They are for the most part pretty good. She knows what suits her shape, flies the flag for British brands and has very good hair.

And, seeing as party conference season this year seems to be a pretty lightweight affair (ref. Boris again), I think Sam’s style is as valid a talking point as any.

Sam kicked things off pretty well when, on Sunday, she arrived at Birmingham’s Hyatt Hotel the epitome of casual chic.

The mum-of -three looked happy and relaxed in a pair of turned up tailored trousers, dark grey V-neck jumper and white pumps.

A day later, and with David now in his best whistle, Sam opted for overdyed skinny jeans (thought to be Topshop) and a dark green Cos jumper complete with this season’s must-have collar neckline.

She finished the look with a pair of fabulous £39.99 “Vamp” court shoes from Zara featuring sexy red tips.

They were easily the coolest thing I have seen on a politician’s wife since Jackie Kennedy donned a pair of sunglasses and put Home Secretary Theresa May’s famed leopard print kitten heels – which made an appearance on Tuesday – firmly in the shade.

So far so good, I was feeling confident that Sam would have a serious statement number up her sleeve for her hubby’s big moment yesterday: his address to the party faithful.

It was not to be. While it is accepted practice for politicians to nail their colours to their ties (although on close inspection David Cameron’s looked more blue than purple) Mrs C’s decision to wear a Joseph dress in...um...Tory blue struck me as safe and uninspiring.

Then again so did Cameron’s speech.

ELSEWHERE this week and poor Jennifer Aniston has been getting a hard time over the size of her diamond engagement ring from fiance Justin Theroux.

One jewellery expert sniffed: “a stone that size is not exactly sophisticated,” while others have compared it to a piece of glass and a bauble you might find in a vending machine.

Harsh words for everyone’s favourite Friend I think.

The sniping put me in mind of a fabled exchange between Elizabeth Taylor and Princess Margaret over the Krupp Diamond which later became known as the Taylor Burton Diamond after Richard Burton purchased the 39 carat stone for his love.

The story goes that Princess Margaret ran into Liz at an event and asked: “Is that the famous diamond? But it’s so large – how very vulgar!”

Canny Elizabeth then allowed Margaret to try on the huge stone.

“It doesn’t look so vulgar now, does it?” came the legendary actress’s reply.
