Sketch for "Formal" - original charcoal figurative drawing

I came across a formal dress that might work in my figure drawings and decided to sketch the model in it.  Maybe this drawing is one that will end up as a painting - we'll see.  I'll post it if the painting works out.  My Able Assistant, Roger, is recovering from eyelid surgery and he isn't able to assist as much as usual, so I've been a little slow in getting new drawings/paintings done.  Amazing how one relies on one's helpers!  This drawing is about 16 x 14" - thanks for looking!
