The exact items I was wearing were things I have owned for a while so will no longer be available to buy anywhere, so I had a look around and have included some links below to help replicate my look from items currently in stores!
My dress and shoes were both Topshop and my necklace was from Accessorize. I managed to find some pretty close dupes of each of my items in high street stores:
The Statement Necklace: Silver Diamante Bib Necklace £12.99 @ New Look
I hope this helped!
