<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">model's position</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for pose that I've seen before include "Assume an attitude (for photo etc)" , "Pretend to be somebody else" , "Models do it for photographic or artistic purposes" , "Pretend; model" , "Sit for a painter" .)
