U.S. Veterans Affairs Assistant Secretary L. Tammy Duckworth has any number of wardrobe challenges as a double amputee and user of a wheelchair, but she consistently looks great. The primary focus of her look is typically on the top half of her body, particularly her shoulders. For this interview on the artificial limb research being done at Worcester Polytechnic Institute, she chose a blouse with an interesting sleeve. (She appears around 1:15)
This layered sleeve gives her a little extra volume at the top of the shoulder, and also allows free movement of her arms, which is obviously important for her in getting around.
