Varsity jackets may have started as a staple of preppy American hunks and college kids, but they're now officially a style perennial, and were seen again as a micro trend on the catwalks for AW15. Thankfully, this means there are affordable versions hitting the high street as we speak.

InStyle's Fashion Editor Amy Bannerman swears by American brand Stewart and Strauss, the original varsity jacket company, who are based in Arizona. They're 100% authentic, and you can even choose a personalised, custom-made version, and design every single detail - from the poppers down to the colour of the cuff trim. The possibilities are endless.

Our favourite thing? You can have your name emblazoned on the back - along with huge selection of patches like tigers, horses and hearts - so your jacket will be truly individual.

The varsity jacket works whatever your style. It's ideal if you're sporty - just dress it down with a slouchy t-shirt, jeans and trainers (this is a favourite look of off duty models). If you prefer classic styling, dress it up with a fitted pencil skirt and stilettos.

And if the palette of the jacket is neutral, it could even be worn as workwear. If you're a very girly girl, a varsity jacket works well over a flippy pretty dress because, slung nonchalantly over your shoulders, as it'll look like you've borrowed it from your boyfriend.

The varsity jacket shouldn't just be reserved for daytime, either - it's versatile enough to dress up for the evening. Just throw a luxe silky version over an LBD for a cool, modern take on evening wear.

Rihanna, Cara Delevigne and Chloe Sevigny are all massive varsity jacket fans, so now you can be in their gang!
