Kate Middleton is known for many things: her amazing blowout, her impeccable style and unfortunately her frequent wardrobe malfunctions. The wardrobe malfunction pictured above happened while Kate was visiting a charity and her Orla Kiely pleated skirt blew up and showed quite a lot of thigh. This was not the first time a gust of wind threatened to expose Kate. The first incident happened on her tour of Canada when her buttercup yellow Jenny Packham dress flew-up while she was at the Calgary airport. Airports seem to bring bad luck for Kate because she had another Marilyn moment at the Brisbane airport when her floral Project D dress flew-up. Now Kate isn't the only royal to have wardrobe malfunctions, Princess Diana and even the Queen have had them. But they quickly learned to put tiny weights in their hems to weigh them down. Unfortunately I don't think that's the best solution for Kate. Most of the Queen's clothes are made by her private dressmaker, who can easily put weights into the hemlines. Kate on the other hand buys many of her clothes from the High Street. It seems a bit silly to put weights in a $50 dress from Topshop, like the one she wore to a friend's wedding that flew up in the wind. I also worry that the beautiful flowing shapes of Kate's dresses will be ruined by adding weights to them. So how can Kate avoid wardrobe malfunctions? She needs to ditch the a-line skirts and pleats and embrace form-fitting sheaths and pencil skirts. Kate has many lovely fitted dresses that she should wear more often, like the Erdem dress she wore when she first arrived in Ottawa for the royal couple's Canadian tour. See, Kate's at an airport and there's not a lifted hem in sight! That's the power of a form-fitting dress. You never have to worry about a fitted sheath blowing up unexpectedly. And Kate definitely has the body to pull off this form-fitting style of dress. Now I'm not saying Kate has to completely give up her pleated skirts. They're clearly a major part of her style aesthetic and they do look wonderful on her. But she should wear them at more appropriate times aka not at a windy airport. Any indoor event that Kate attends where there's no outdoor walk-about is the perfect occasion for an a-line dress or skirt. Or Kate should check the weather before she goes to outdoor events to make sure it won't be too windy for her flowing skirts. I do this in my daily life and I don't have a personal secretary who oversees every detail of events I attend. Surely Kate could ask her secretary for a daily weather update. But on those windy days Kate should just stick to fitted dresses or a pencil skirt. It's a more appropriate look for a future Queen and the mother of the future King. UPDATE: Kate didn't follow my advice because she had another near-reveal when her fit and flair Catherine Walker coat flew up at the New Zealand airport. Airports and Kate really don't mix well.
