I'm in my late 20s and am not ashamed to rock this like a school girl. I love me some Hello Kitty!! This backpack is absolutely adorable and you'll definitely get a lot of compliments (mostly from little girls, but who cares). This is definitely a child's backpack. I am petite (5' tall) and this backpack fits me well but does look a smidge small in proportion to the rest of my body. So I'm not sure how this would work on someone who is taller or with a bigger frame. It is well constructed but I wouldn't use it for a ton of heavy textbooks for school or anything, because it doesn't look like it would hold up to that kind of weight. The sequin bow is cute as hell but you definitely need to be careful with it because the sequins tend to get snagged pretty easily. More fashionable than functional, basically. But definitely worth the money if you are a HK fanatic!
