She was an extravagantly slender girl. Her ribs showed. The conspicuous knobs of her hipbones framed a hollowed abdomen, so flat as to belie the notion of “belly”. Her exquisite bone structure immediately slipped into a novel- became in fact the secret structure of that novel, besides supporting a number of poems. The cup sized breasts of that twenty-four year old impatient beauty seemed a dozen years younger than she, with those pale squinty nipples and firm form.
-Vladimir Nabokov, from The Original of Laura
