I have never gone to an official formal event like this. Will a Montana ball be truly a fancy ball, I don't know. I have a long but simple black dress that looks great on my 6'1" somewhat slim frame. The ball is happening the second week of February and the possibility is that there will be snow on the ground. What do I do for a "coat". I have a remarkably long sweater coat - as long as the dress. Is that retarded? Perhaps a bollo faux fur shrug would be more appropriate? Also, I have silver sandals that are open toed. Do I wear stockings with that even though they are open toed? If so, what kind? Any ideas?
