Let's cut to the chase: I'm 30 and pregnant - not the target demographic, in any situation, for wearing pigtails, even if they were the hairstyle of choice at Marc by Marc Jacobs New York Fashion Week show.The last time I tried this hairstyle, I was 18 and at a "skool disco" in a Glasgow club called The Garage. Drinks were a £1. Everyone's white shirts were open to the navel. I think I was wearing a whistle.
So, here's what I learned from wearing pigtails when you're not a Marc Jacobs model:
1. You can't wear them with heels. That would make you look all sexy and come-to-bed, rather than clean, neat and ready for anything. You need to wear them with a boot or a masculine flat, like a brogue.
2. Keep make-up minimal. It's got to be lipstick or eye-liner, I'm afraid. Also, anything more than one solitary sweep of blusher channels jolly milkmaid.
3. These pigtails should look functional. Pleat your hair close to your head and use a serum to keep everything looking smooth. The last thing you want to use is volumiser - this will take the style from MJ girl to Kelly Brook bombshell on a lingerie shoot (sexy? yes. Fashion? No).
4. If you're wearing them to work, team the hairstyle with something casual. I will only say this once: absolutely, under no circumstances, should you wear pigtails with bodycon. Layer up and accessorise with a backpack. These pigtails would look brilliant with anything by Christopher Raeburn.
5. They are extremely anti-ageing. Honestly - when I decided to try this out, the word mutton sprang to mind, but then I got ID-ed for paracetamol in Sainsbury's. Day. Made.
