Boxing gloves would be the easiest.  Poser fingers bend that way, and the hand doesn't need to change.  What I'm talking about, and it really has nothing to do with gloves, is that the Poser "hand" is just a solid piece.  Mine changes shape.  Hold your hand up and move the fingers toward the thumb, and vice versa.  Because the hand in made of individual bones that can move independently, within limits, you get a crease where the red line is.

Try picking something up bending only your fingers and thumb.  It's not very pretty (see picture), yet that's the way Poser people do it.  No wonder there aren't too many fat ones.
