@iutami AFAIK, not in the foreseeable future. Despite needing less materials, kids blanks for the imprint market can cost as much as or even more than the adult sizes at wholesale.
Additionally, Mediocritee would have to validate compliance with all CPSIA regulations. This is a considerable expense that is unfeasible for the current selling prices here. Also, the smaller shirt sizes will require another set of printing screens, adding additional cost.
