My Hikaru and I bought our wigs on amazon from the same person at the same time, and cut and styled them to our preference. Our jackets we also made, which may be your best bet if you want an accurate one. also, if you have an entire host club, its very benificial to make them, so you know they are all the same shade and style. but that's the perfectionist in me. If you are looking for premade, check ebay.
the nice thing is we are already twins, so we have everything else down perfectly lol
