Preen Line - Designers Thea Bregazzi and Justin Thornton draw inspiration from the bohemian style of late singer Janis Joplin to create a feminine Pre-AW19 collection for Preen Line, which includes this black Rosalba midi dress, first seen in the lookbook. It's made from semi-sheer georgette printed with charming prairie flowers, then complemented with a matching slip underneath. Cinch it at the waist to balance the loose-fitting silhouette before adding chunky boots.
