in the buff

naked. informal
The original meaning of buff in English was ‘buffalo’, and it later came to mean ‘ox hide’ or ‘the colour of ox hide’. In the buff itself comes from buff leather, a type of yellowish-beige ox hide formerly used in military uniform, the colour of which was regarded as comparable to that of human skin.
