I agree a V neck seems to help with small hands the V fits your palm and the hand can wrap around the neck better

The way I was taught to play the point of the V sits on the ball of the thumb. Or perhaps more correctly, the ball of the thumb is touching the V, as it's not there to support the neck.
I suspect that the idea of wrapping your hand around the neck is often the main source of the problem for those that say their fingers are too short.
