Staying warm in winter without looking like Joey Tribbiani (aka wearing all the clothes) is not an easy feat. While I have no problem waxing lyrical about the joys of a stunning statement jumper, sometimes, the reality of surviving the cold months is a little less glamorous, particularly when you're making the rounds of the local park (for the 100th time). It was whilst interning that I picked up on one particular layering hack that has seriously changed my winter dressing game. I was told that the fashion editor's secret to keeping warm whilst still looking pulled-together and polished was a distinctly practical-looking £40 gilet.
