watson cross
Standing with the legs crossed at the calf-, knee-, or thigh-level.
This pose is named after actress Emma Watson, who has famously and frequently adopted this pose, usually at various award shows.
The character is usually deliberately presenting or shown in this pose (rather than, say, simply walking). Sometimes, they will have one hand on their hip.
Legs crossed at the ankles, as in Danbooru post #91772, don't count. One leg hidden behind the other, as in Danbooru post #2607422, also doesn't count.
