Hello Elizabeth, if you order standard size now and use the fastest shipping method (Premium Express, 3-6 days shipping time), it will reach you around early November. I'm sorry to say that the item won't be able to reach you on or before Halloween. n_n
*All shipping information (including methods, cost & estimated delivered date) will be shown in order page, before payment; you can pay extra cost to upgrade shipping method there.
*Please remember to mark down the date (you need it) in the order form when you order it. :)
