Hello Kpop, our tailors need about 12-17 business days to make the costume (standard size & custom-size) for you (excluding shipping time), so if you order now, it will not able to reach you by 30th Oct. However, we have a list of our ready-to-ship costumes & wigs at [ http://www.cosplayfu.com/readytoship/ ] provide with the standard sizes ['In stock(size)']. If you order them and choose faster shipping methods, they will be able to reach you before Halloween. :-)
