Wearing cozy knitwear is not just for keeping warm on a cold day – it can also be a hot choice for the bedroom. Jennifer Aniston recently graced the cover of Variety magazine showcasing her sex appeal in a simple white jumper and hat. Despite being 50 years old, the actress proved that comfort doesn’t mean sacrificing style or desirability. Sarah Harrison had model Florence Mueller, 24, from central London, review six different knits from the high street, giving them a rating out of five for their sexiness.
