Hello kylah, if you order standard size now (about 2-3 weeks making costume time) and use the fastest shipping method (Premium Express, 3-6 days shipping time), it will reach you around Halloween. (n__n)
*We will try our best to hurry up the order process, but we cannot 100% guaranteed the exact delivered date, hope you can understand.
*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, so we will alert and put it into our higher priority list. :)
