The Helmi sewing pattern includes two variations: The straight-cut blouse has elements from the classic trench coat, such as the cape and sleeve straps. The rounded collar and slightly curved hem with slits add a touch of soft femininity to this shirt. The more streamlined tunic variation is also straight-cut and has a simple stand-up collar, half sleeves, and a curved hem. Both variations have a discreet and elegant hidden button placket.
