'slender-hipped' originates from the combination of 'slender' and 'hipped', where 'slender' meant 'thin or narrow' and 'hipped' referred to the hips.

'slender' changed from the Old English word 'slinder' and eventually became the modern English word 'slender'.

Initially, it meant 'thin or narrow in form', and this meaning has largely remained the same in modern usage.
