Ok, this is a very minor pet peeve ...
I notice that many T-girls of various stripes have their fingers splayed out (fingertips separated making the hand wider) when posing, as if they were palming a volleyball .
I think it's more feminine (and looks better, too!) to keep the fingertips close together -- it seems to make the hands look smaller and longer.
It seems to me that GG's typically have their fingers relaxed and together in pictures, while many T-girls are spreading them out (perhaps to draw attention to their nails?) -- but to me it makes the hands look big, and it seems like a masculine thing to do.
Ok, I'm ready for the onslaught of photos of GG's with spread fingers ...
