Someone did a GM reveal and I thought it looked great on her, it didn't look huge at all! I haven't seen the artsy IRL and i thought I would for sure be getting the MM, but now I am thinking maybe the GM, I really like big bags though...If you're not really comfortable with it, or it makes you self concious, I would probably return it. Maybe try it around at home for a few more days and if it still doesn't sit right, I'd take it back and try the MM. Good Luck with your decision!
