i think it should be accepted. i see shirts like this all the time on the street and threadless seems to have the capability to do anything really at this point.

plus it rocks.

i remember hearing word that it's difficult for the printers to line up belt-print with other styles of printing (the eyes might not end up where you want them), but i'm not entirely sure how they do the printing.

On the website it says 'A submission will be declined if it's too large for traditional printing and also not suitable for belt printing. Common oversights with placement include designing across the tee from edge to edge, carrying a design over a seam onto the sleeves or off the top of the shoulder. We love larger format prints, but a design meant for regular screen printing should be constrained to a 15" x 20" (38cm x 50cm) area.'

but then they printed this

so i dunno what do think :p
