From old site:
Wrist-hugging is properly preformed when the hugger, leans in towards the huggee's arm as the huggee raises their arm towards the hugger. Proper positioning should be roughly as shown in the first image (Right).
The hugger should embrace the wrist gently and come close to leaning your head on the arm but it is considered improper to actually touch outside of an intimate relationship.
The Huggee however should remain limp wristed throughout the duration of the hug and refrain from any improper action with the hand, their other hand should remain at their side, or possibly on a glass of wine depending on the circumstance. try not to wear any jewelry on the wrist you offer to be hugged to avoid any embarrassing situations. After what is decided as a comfortable time separate, the hugger leans back upright and the huggee lowers their arm. at this time initiate conversation or whatever action the situation calls for.
