Hello Rob Gilham, we are afraid it is unable to reach you before 20th Jan. if you order now. Our tailors need about 2 weeks to make this costume and the fastest shipping (UPS, 4-6 days shipping time), it will reach you around 25th Jan. 2013. :)
For the blue garments, do you mean the T-shirt & top, if so, yes, they are included, as the photo shown. n_n
