I'm no Taiwanese babe but I'll sure try! Puffy is the name of a clothing line from the largest island in the Republic of China. All their clothing comes one size or 'free size' as they say. My size! Yipee! The shirt says, "Good evening. How many?" Is this the tiger making a reference to having you for dinner? Not sure. Probably just bad translation. At any rate, I'll bite!
P.S. This is the worst picture I could find of the girl. I just couldn't help it. Even so, ain't she the cutest?!
