G-STAR original trench coat style made of dark blue denim. - Brand: G-STAR - Color: Dark Blue - Material: Denim - Style: Trench Coat Thank you for viewing. Worn only once. I think it would be cute to wear this denim over an all-white outfit or a striped shirt. Trench coats usually bring to mind a beige color, so this denim trench coat is cute because it's unique and you won't see it on everyone else.
