Dusen Dusen Navy Dress size 10

Dusen Dusen sleeveless swing dress in navy grid pattern. Dress is tagged as a 10, however I would say it runs small by a size, especially in the chest and waist. Material is a heavyweight cotton twill, like a denim. Flat Measurements: Pit to pit: 17” At waist: 15” Shoulder to hem: 34” Waist to bottom hem: 18”
