Fifi Leigh
Jackie Kennedy Onassis style
Short dress and cropped jacket, one-strand pearl necklace, oversized sunglasses, short-sleeve or long-sleeve merino wool navy sweater, white pants whether corduroy or denim, beige Karl Lagerfeld loafer-style slingback with stacked heel, black turtleneck sweater, black trousers and black belt, classic beige trench coat, and print scarf for accent. These items are functional and practical, in which you can mix and match to wear them differently into many different outfits.
I think Jackie is fashioable because she is French, Conservative Republican, and the wife of former president JFK, in which she opted for a clean wardrobe to appear professional, respectable, and classic as the First Lady.
