Design duo Kolchagov Barba have shared a sketch of the gown they created for Piper on Instagram.
Kolchagov Barba is a couture label founded by Bulgarian designer Svetoslav Kolchagov and Italian marketeer Emilio Barba in 2011. They say they view dresses as "unique pieces of jewelry cast to decorate, enhance and embrace women's bodies."
After the ceremony Piper's makeup artist Toby Salvietto shared a photo of the happy couple on Instagram, which shows Piper's dress in all it's beauty.
The compliments started flooding in.
And the designers tweeted their reply.
It was the second time that week Piper had worn a Kolchagov Barba gown.
She stepped out in a pretty pink party dress, which she teamed with Kat Maconie heels, to make an appearance at Simon Cowell's Music Industry Trust Awards on Monday 2 November.
