It was a Project Runway family affair tonight at Johan Sebastian Grey‘s debut New York Fashion Week show, where the designer presented his Fall/Winter 2020 ‘Lineage’ collection in partnership with the Fashion for a Cause Foundation. Grey, who won Season 17 of the design competition, showed a collection of rich textiles, woven leather, and vibrant colors inspired by his Colombian heritage.

Karlie Kloss, Christian Siriano, Brandon Maxwell, Elaine Welteroth, and ELLE Editor-in-Chief Nina Garcia sat front row, taking in the ready-to-wear line of bustiers, quilted silks, and expertly crafted leather bags and belts. Ahead, all of the looks and details from Grey’s debut collection.
