Shirts are an accessory in Graphictoria that can be created and bought in the catalog in the drop-down named, "Shirts". Like pants, these are a clothing item that can be made publicly for 5 Coins, Graphictoria's currency, and can be bought for more or less of that price.Creating Shirts:
Creating shirts is the same process as creating pants, it is done by using the shirt/pants template currently found here, and editing it in any visual editing software such as Paint.net, GIMP, Adobe Photoshop, etc.
Fun fact: In the first version of the shirt template, there was a typo on the top left corner. It said "GRAPICTORIA" instead of "GRAPHICTORIA" - you can still see this older template with the typo here.
After creating the design desired, uploading the shirts is done by going to the "Upload" section in the catalog drop-down and then choosing your file, name, description, and by clicking the "Type" selection at the bottom, and selecting "Shirts". This process takes 5 Coins to do so.
