Medallion brocade white and blue sundress

This beautiful white and blue sundress is to die for. The photos are of the actual dress so the pattern is exactly as appears! I bought it off posh but it was a little to snug on my chest. Would recommend a 4-6 with a chest smaller that 36D/34DD. I believe this style was also sold on Lulu’s and at Francesca’s but the brand is Everly!
