Everyone loves a game of cowboys and Indians and we are sure you ladies are the same! Western fancy dress is a great couple costume too, whether you go down the Cowboy and Cowgirl route, or one of you dresses up as an Indian, complete with headdress and tomahawk! Saloon girls also make a great ladies western fancy dress costume, as it is something a little bit different to the usual outfits you see at these type of parties.
