But everyone was dying to know what Kate would wear too, seeing as it definitely wouldn’t be a bridesmaids dress (protocol oblige). It turns out the Duchess made a subtle nod to her own wedding day, by choosing an outfit by Sarah Burton at Alexander McQueen.
The pale pink silk midi dress featured bell sleeves and a cinched waist, and she accessorised it beautifully with a matching fascinator and suede heels.
Normally everything she wears sells out instantly, but sadly this one is custom made, so you won’t be able to buy the exact one. However, we found this very similar style, also by McQueen.
We reckon it’ll go fast though, so be quick if you want to recreate Kate’s wedding guest look.
