that would probably depend on the t-shirt used (quality, model.. as in neckline, fitted or not, colours jaddah-jaddah..), the characters used (what will they say?), and um.. i havn't eaten yet so my english is off by quite a bit, and "font" isn't really the right word here.. the style of the characters, maybe? (brush-strokes, typewriter etc..) and the layout of them on the t-shirt, as well as the colour of both t-shirt and characters.
but yeah. in my opinion, korean characters are very pretty. :3
