The blouse has a small lapel collar, small shoulder pads, long sleeves with cuffs and flattering draping over the bust (yokes). It is lightly tailored, and together with the small shoulder pads, the blouse creates the iconic hourglass silhouette with full shoulders and slim waist. It is made in Bloomsbury's soft and breathable signature fabric, and closes with four mother-of-pearl buttons on the front.
Note that the video of the white shirt is only to show the shirt - this one is black.
