MM usually looks great, her choice of clothes suits her personality and style. that floaty frock is the first item of clothing I've seen her wear that I didn't think suited, or fitted her well.
We all make mistakes don't we. Stand up anyone who always looks a million dollars, even at a wedding. I recently saw some photographs of myself at a wedding several years ago. On the day I felt fine, loved the outfit. On reflection it was just not right for that wedding. I'm so relieved no journalist is sitting pouring over the worse photographs of me they can find, to confirm I never had any taste.
36 is not old. If MM wants to wear her hair lose, why shouldn't she. Many of the young women in their mid 30's I know have long, lose hair. Why should MM be any different?
