Hello Tanya Landrygan,we are afraid that the time is a bit too rush to reach you by 7th November.
The fastest processing time of this costume is about a week,if you order it now and use the fastest shipping method (Premium Express, 3-6 days shipping time), it will reach you around mid November.
*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. :)
