Hello Simon Fielder
, yes, you can buy item(s) separately, but the unit price will be high (because the international shipping cost), please submit ticket (with product link & request) to our Support Center and let my teammates help you directly 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 early 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. :)
