Cat Deeley never lets us down with her perfectly put-together outfits, and this week the This Morning presenter has been giving us major office outfit inspiration for the hot, sunny weather with her smart-casual looks.

On Thursday morning, the ITV star looked effortlessly stylish in a sleeveless floral blouse with a pair of white, flared jeans. With the hot, sticky temperatures of the heatwave, I've been searching for the ideal heatwave-friendly yet smart, office blouse for some time and Cat's Boden top is one of the best I've come across this season.

Cat, 48, kept her look pared back, leaning into a quiet luxury look; polished enough for an office or smarter occasion - ideal if you're not one to wear a dress or skirt. Her Madewell jeans (get the look with this £46 M&S pair) and Stuart Weitzman sandals completed her look.

The floral blouse features a ruffled neckline that's versatile for everyday wear – and if you're dressing for the office, I'd recommend channelling Cat with wide-leg smart trousers and Mary Janes or loafers.

The blouse is available in navy and white polka dots, which can be easily dressed down for a more laid-back finish. I could totally see the top tucked into blue jeans or shorts,  to create a feminine silhouette and paired with chunky sandals or ballet flats.

The relaxed fit is flattering on every figure, and when paired with chunky gold jewellery and a tan or brown summer bag, it's giving Hamptons vibes in your office. It's also 100% silk, which elevated the blouse even further with its silky, soft finish.

It's such a popular blouse that's it's selling fast, so I'd shop quick if you want to copy Cat's exact look.

You don't need Cat's exact blouse to get the same feel - the high street has plenty of pretty, floral sleeveless blouses with ruffle detailing, a la Cat. 

The Phase Eight Junie Blouse has a pussy bow neckline, which gives an even smarter look to the blouse, and is on sale for £28.80. The Dara Blouse from Crew Clothing has a similar ruffle and floral combination, and is only £23.

And perhaps my favourite is the Hobbs Sadie Blouse, with a big bold floral print and sweet ruffles on the sleeves.

As always, it's been a stylish week for Cat, who really does give me the best inspiration for what to wear in this weather when I'm heading to the office.

Monday's look was perhaps my favourite, as I love a peasant blouse and Cat's gorgeous embroidered top is just what I want to be wearing with jeans right now. The Wrap London top has since sold out, but I found this stunning version at Sezane, which I've already snapped up; the embroidery and shape make it look far more expensive than the £100 price tag, and it's the sort of top you'll pull out summer after summer.

Or pop to Next for the Love & Roses Floral Embroidered Blouse, £42.

Another classic Cat look this week was a Mint Velvet co-ord, with Cat wearing both the Polka Dot Tie Neck Blouse, £58, and the matching Polka Dot Midi Skirt. 

Cat changed the game on Thursday's show, wearing a wedding guest-ready pink cowl neck silk dress from Massimo Dutti, £120. The draped, flowing dress had an ethereal feel to it and was stunning on the mum-of-two.
