In one of the unpublished Tolkien essays sitting around in the Bodleian library, Tolkien went into some depth about Gollum.
Gollum was according to Gandalf one of a riverside hobbit people – and therefore in origin a member of a small variety of the human race, although he had become deformed during his long inhabiting of the dark lake. His long hands are therefore more or less right. Not his feet. They are exaggerated. They are described as webby (Hobbit 88), like a swan’s (I. 398), but had prehensile toes (II 219). But he was very thin – in The L.R. emaciated, not plump and rubbery; he had for his size a large head and a long thin neck, very large eyes (protuberant), and thin lank hair . . . He is often said to be dark or black. At his first mention (Hob. 83) he was “dark as darkness”: that of course means no more than that he could not be seen with ordinary eyes in the black cavern – except for his own large luminous eyes; similarly “the dark shape” at night (I 399, 400). But that does not apply to the “black (crawling) shape” (II 219, 220), where he was in moonlight.
Gollum was never naked. He had a pocket in which he kept the Ring (Hob. 92). ... He evidently had black garments (II 219), and in the “eagle” passage (II 253),10 where it is said that from far above, as he lay on the ground, he would look like “the famished skeleton of some child of Men, its ragged garment still clinging to it, its long arms and legs almost bone-white and bone-thin”.
His skin was white, no doubt with a pallor increased by dwelling long in the dark, and later by hunger. He remained a human being, not an animal or a mere bogey, even if deformed in mind and body: an object of disgust, but also of pity – to the deep-sighted, such as Frodo had become. There is no need to wonder how he came by clothes or replaced them: any consideration of the tale will show that he had plenty of opportunities by theft, or charity (as of the Wood-elves), throughout his life.
