Here is Mary-Kate Olsen walking her pooch in New York. Whilst we love her outfit, particularly the crisp white shirt (a wardrobe must), we would like to highlight the pitfalls of wearing a midi-skirt if you are short. As the 5' 2" Mary-Kate shows, it only makes you look shorter. Like, totally teeny-tiny. So whilst we commend you, readers, for wanting to stay on trend, certain styles are to be avoided depending on your body type. Rain macs, too, are best left to those above 5' 7". Why do you think runway models are always so tall? (the newly married Kate Moss is an exception here). As for Mary-Kate, we can only presume she has enlisted her dog on her quest to find missing sister Ashley. (We say missing, as the fashion press only ever seems to talk about Mary-Kate...strange).
