I combined a white bodysuit and a Red Vest, to make a Christmas outfit (or for any occasion, really) for my grand baby.  The sizes and manufacturers are different BUT they fit as if they were bought together as a set.  See tag photo for more details.  White Bodysuit: 95% COTTON, 5% SPANDEX.  Red Vest: 100% COTTON.
Besides trying to keep S/H as accurate as possible, I will also combine shipping.
