Can I bring my own shirts

Would you bring in a meat patty to McDonald’s or a chicken to KFC? We prefer that you do not bring your own shirts because of seams, pockets, zippers, and material. Many garments purchased over the counter are not print or embroidery friendly. When Alaska Serigraphics provides both the shirts and the decoration, we stand behind our work and cannot do so if you provide the garment to us. Of course if you whine loud enough we might just do it.
