So I took a look. First at the general furnishings and the closest thing I could find would be the wardrobe, but that may or may not have anything in it. There was even a butt on the list. Then I wandered over to magic user furnishings and found spatulas, tweezers and stuff animals(so you could find Elmo), but still no socks. Then it was on to religious furnishings where I saw cassocks, cloth, robes and vestments, but no footwear was to be found. Then I saw misc. utensils and personal items and thought, "Aha! It has to be here." Alas, while it had such things as earspoons, wigs and thongs(wonder what they did with those), there were still no socks in sight. Then at last I got to clothing and footwear and this is what I found. Boots, hose, leggings, sandals, slippers, and even stockings, but socks seemed to have been omitted.Appendix I of Gygax's DMG has a lot of random charts, including one for condiments in a kitchen. But I think it omits haberdashery.
It seems you were right!
