- IMPORTANT: We Created a Unique Sizing Chart Just for Illo Coast Shirts, Make Sure To Reference Our Size Chart To Help Make Sure Your Pick the Size That is Just Right for You! Keep in mind this is our size chart not to be confused with the one Amazon offers. It's different! - Triple Quality Control: In at least three places throughout the production of your shirts, a human being checks each shirt against the original artwork preview to make sure that the right artwork is printed on the right shirt, the print is of the highest quality, and everything looks the way it should. Most problems are caught and corrected before the shirt ever leaves on its way to you. - PRINT QUALITY DIFFERENCE: We use only Kornit Avalanche printers to produce the finest-quality images possible that won't wash out of the shirts
