Hello Thomas Retcho, we are afraid the time is too tight, it is unable to reach you before Halloween.
*if you order standard size now (about 4 weeks making costume time) and use the fastest shipping method (Premium Express, 3-6 days shipping time), it will reach you around 5 weeks after your order's paid & confirmed.
*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. :)
The price for boys & girls or adults are all the same.
*Custom size costume doesn't charge extra cost, but the processing time will be longer than standard size costumes; for this costume in custom size, we need about extra 1-2 weeks to make it (excluding the shipping time).
