Create a fun first layer with girls underwear and boxers from Old Navy. Our bras and padded bras provide reliable comfort and support, while our underwear, including bikinis, hipsters and boxers, feature a fabulous assortment of cool colors and pretty prints. Snap up girls underwear three-packs and seven-packs for even more variety and value. And they may be borrowed from the boys, but our girls boxers have plenty of feminine flair.
