Need Photoshop / Illustrator Help to Enlarge & Smooth Out Edges

[TechKnight]

Can someone please help me? I am in the process of making a t-shirt for a Halloween Party but can't for the life of me figure out how to enlarge a silhouette without pixelated edges. Can any elite photoshoppers or illustrator users help me out?

This is what I have to work with. I would like it 200%-300% larger (2X-3X) with smooth edges for a curvy look.

(Larger is always better since I can always shrink to fit.)

This is the ideal T-Shirt:

Please email the file to me at DariusIS@gmail.com

Also if you have any suggestions to the wording, I am definitely open to adjustments!

I don't have much to give to the best artist except what's posted in the freebies forum but I'll be happy to send the winning artist an actual tee that is produced (from iron-on transfer paper).

Illustrator is your friend. Photoshop isn't going to help you enlarge that.

when I expanded it in photoshop It seemed to be clear enough, in fact, it brought out a lot of details of the pic I had not seen before.

Inkscape, which is free, has a tool to convert raster graphics to vector. It should handle a relatively simple black-and-white image like that fairly easily. You can then export as an arbitrarily large PNG.

Edit: To prove the point, it took me two minutes to generate an SVG and fairly large PNG version. The halo could use touching up.
