Hello Ruby, yes.
If you order custom size around 1st Dec. 2015 (about 2-3 weeks making costume time) and use the free standard shipping method (20-30 days shipping time), it will reach you around late Jan. 2016.
*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. :)
