A great satchel adds some structure to your bag collection. No handbag assortment is complete without the ultra-classic style, typically a semi-structured top-handle bag with adjustable straps, modeled on the bag once used to carry schoolbooks but now a staple in modern wardrobes for its practicality while still being pretty, function while still being fashionable. While a classic satchel's shape and size remains fairly constant, satchels now come in all sorts of styles, from colorblocked to simple cognac, tasseled, embellished and embroidered, and often they include a detachable shoulder strap for even more ease of carrying. The perfect satchel works as well with a suit as it does with a sundress, and easily transitions through all seasons. Make the grade with the schoolgirl standard-turned-fashionista fave.
