Size 4 Polish, simplified. This tank has a high neck, slight A-line shape, and hidden zipper up the back. Plus, it's made of our drapey, wrinkle-resistant Japanese GoWeave. Dress it up with trousers, or keep it casual with denim. I realize it's quite wrinkled in the pictures, that's just the nature of this fabric. It smooths out completely with a quick ironing. I will iron it before I ship it!
