First thing first, you need to determine which Tifa costumes you are looking to cosplay. Since the original Final Fantasy VII game, there have been several costumes made for Tifa. This guide has five different costumes to choose from, but there are even more costumes such as the cowgirl costume or the dresses she wore in the flashbacks when she was a young girl. Once you know which costume you wish to make, you may start finding the necessary items, supplies and equipment to make them from scratch. Otherwise, you can purchase them on various online platforms as ready-made costumes. Do pay attention to where each accessory is placed and style the wig accordingly. Make-up is also very important to enhance the looks. Finally, it is important to know her personality, her usual expressions and unique stances so you know how to pose at cons!
