When not in a uniform, Swiftwind tends to wear what shi calls her "civilian uniform" - a corset, and a reproduction leather bomber jacket that was a gift from a close friend. Oftentimes shi'll aim for something low-cut, especially when shi strives to impress, but when shi just needs to dress casual, shi'll go for whatever is comfortable and clean that day.
