This Morning host Cat Deeley looked glowing in green when she arrived at the 2025 National Television Awards - and she even matched with her co-host Ben Shephard's green velvet blazer.
I was absolutely convinced that after wearing red three times at the NTAs, Cat's colour choice for this evening was a given, but I was surprised to see she chose another festive colour instead.
Her beautifully elegant green gown immediately reminded me of the silk dress Keira Knightley wore in Atonement. It's surely one of the most iconic on-screen looks of all time, and the daringly low-cut back of Cat's style, along with the fluid silhouette and draped detailing, has a really similar feel.

Copy Cat's dress
Her green goddess gown is by Oscar de la Renta, and whilst the bad news for anyone who's fallen in love with it is that the RRP is £7,515, the good news is you can buy it with a whopping 70% off at The Outnet.
Or if £2,255 is still a bit more than you were hoping to spend, I've found some designer lookalikes that will make everyone else green with envy. The Reiss dress is well worth the investment.
Oscar de la Renta is one of the best designer labels in the business, and I absolutely love the fluted, floor-length skirt and asymmetric draping on Cat's exact dress. If you have even the vaguest possibility of a black tie event on the horizon and your budget will stretch that far, it's truly stunning.
This is a slightly darker green hue than Cat's dress, but the draped ruffles really make it stand out from the crowd. It's available in UK sizes 6 to 20, and it needs minimal accessories to look very sophisticated.
This is very Keira Knightley. I don't even have a red carpet-worthy event in my diary, but I'm figuring out how I can justify buying this absolute beauty! Wear it with your hair up to make the most of the neckline.
How to style yours
Look closely and you'll notice Cat's gold jewellery and matching handbag. She layered up on chunky chain cuffs and bracelets, adding tassel earrings and a vintage-inspired clutch bag.
What's a gorgeous green Reiss gown without a gold cuff to wear with it...? This brass bracelet has an adjustable cord fastening so you can get find your perfect fit.
You might be excited for the return of Topshop for its Joni and Jamie jeans, but the jewellery is well worth checking out too.
M&S is my go-to for jewellery that looks much more expensive than it is. These tassel earrings have pretty little pearls on the end for added interest.
As if the front wasn't fabulous enough, the back of Cat's dress was cut daringly low. She styled her wavy hair with a side parting to continue the vintage vibe, and kept her make-up and nails subtle to allow the dress to do all the talking.

If you're asking yourself what colour suits me, green can complement lots of different skin tones and hair colours. And although the easy thing to do is add black or metallic accessories, don't be afraid to clash with another pop of colour. I love how it's styled on The Outnet with a hot pink clutch bag, or you could even try a statement piece like a leopard print handbag.
