Is it possible to seal a tshirt painted with poster paint?

ive painted a tshirt with poster paint, it looks good now but will inevitably run. is there anything i can do to seal it? i only really need it for one night. thanks

Well, you could try spraying it inside and out with a fixitive such as Krylon "Preserve It!"... Though I suspect that will make the fabric (even more) uncomfortably stiff, and I'd worry that poster paint is going to be too brittle to stand up to much wearing. Next time you might want to consider fabric paints.
