Claudia Winkleman’s Graham Norton Show shirt is from this high street store

The Traitors may now be over but we're still getting a chance to lust over Claudia Winkleman's outfits as she took to our screens on Friday night to cover The Graham Norton Show while Graham is away. The BBC host – who was joined on the sofa by stars including Chris Pratt, Toby Jones and Rob Beckett – looked elegant in black tailored trousers and a black silk shirt – and we've found exactly where you can buy it yourself.

Claudia's go-to stylist Sinead McKeefry – who was also behind the star's viral Traitors outfits – had clearly received lots of requests asking about this black shirt, as she posted on Instagram stories: 'For all the lovely people asking the blouse is @reiss', before linking to the exact product – and it's still in stock in most sizes.

Claudia wore the Reiss Hailey Silk Shirt in Black, which costs £198 and also comes in five other colours. This chic design features oversized cuffs, concealed button front closures and a pointed collar, and can be dressed up or down, looking equally as good with tailored trousers and skirts as jeans.

This timeless design comes in regular and petite fits, and while most regular sizes are still in stock, sizes are selling fast in the petite line.

If your size isn't currently available, it's worth keeping an eye on the page in case it comes back in stock, or shopping some of these great alternatives we've found. M&S's Autograph range has a black Pure Silk Collared Shirt for £89 and currently available in all sizes from 6-24, while Next is selling this Friends Like These Black Satin Button Through Shirt for £35; it's polyester instead of silk, but still has a similar look.

Claudia isn't the only famous face who's a fan of high street store Reiss; the Princess of Wales has regularly worn pieces from the brand in the past, including these Thea leather Chelsea boots, currently reduced from £198 to £158, and this double breasted camel blazer, now less than half price at £110 (but only available in a limited number of sizes).

And if you're still dreaming about Claudia's cosy and cool Traitors wardrobe, you can still shop some of the exact items she wore, including this classic grey ME+EM Check Wool Trench Coat, and these SPANX Care Seamless Leggings.
