Hello shanley, if you order now, the processing time for the costume is about 3-4 weeks (excluding shipping time), while standard shipping will take another 20-30 days to deliver your package, so it will probably reach you around early October.
*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. :)
