Introducing the Collia Dress. One of the hero pieces of our Spring 2025 runway show and our Founder and Creative Director, Rebecca’s, favorite, Collia Dress debuts with a diaphanous chiffon designed from 100% silk. The viscose, drapey chiffon gives this piece a Bohemian-inspired look and feel. This stunning event gown features a plunging, deep v-neckline with a cape around the shoulders, lovely boho-inspired bell sleeves, a multi-tiered skirt that goes high-to-low at the front then levels out around the hem. Delicate ruffles adorn each tier and the cape. A chiffon self tie detail sits at the back with an open slit. This piece comes fully lined and includes a side seam zipper. 

  • 100% Silk

  • Side Seam Zipper 

  • Deep V-Neckline
