I can't figure out what the problem is with this dress. It makes her look like she needs a bra with better support. However, from the time I worked in lingerie, the standard for fitting was the mid-point of the bust should be half way between the shoulder and elbow, which it appears to be for MM. All in all, it looks like a dress made in a 7th grade Home Economics class. Those shoes are a nightmare and her hair looks like a bad wig.
I don't understand MM. She rarely presents a polished appearance. Most of the time when I see pictures of her, I don't see a 38 year old crown princess, I see an 18 year old college freshman hanging out with friends. Unfortunately, she is 20 years too old for that look. If she didn't want the position and doesn't want to do it properly, she shouldn't have married into the family. If she doesn't know how to dress appropriately, then she should hire someone to help her. She just doesn't seem to present the kind of appearance you would want representing your country.
