Luisa Font 

http://www.myfonts.com/fonts/tipotype/luisa/

Luisa is a typeface with two weights: regular and inline. Its design responds to the calligraphic principle of pressure. It combines the elegant qualities of the calligraphy with the unstructured and informal layouts of modernity. It is suitable for striking composition in words and short sentences and for shaping dense and deep textures when applied into paragraphs.
