Hello yaya, this costume does not include the wing. So, if you buy the wing separately, you can check here   http://www.cosplayfu.com/product/Angel+Wing+%28Black%29 . All items in " Accessory Package" are available only when order size is $50 or over. If you buy this separately, the price will be much higher. n_n

Hello  mouse2012, I am afraid it is the unique size.
