For customizations that aren’t featured on the site, yes. Otherwise, proofs are not offered because the photographs and mockups pictured are reasonably representative of the actual item you will receive. There may be slight differences for color variations because different digital screens display colors different, and certain clothing sizes may slightly affect trimming of design elements near the borders/edges. For quality assurance, I have also ordered product samples to ensure the quality of print, colors, materials, and design placement.
