British model Sam Rollinson, after Chanel, Paris, October 2015.
Sam's vintage/antique brooch caught my eye... a really cool way to wear a brooch that perhaps you have inherited from a relative or purchased at vintage shop but aren't quite sure when or how to wear it. Pin it to a suede (although mind the pin marks — not sure how you avoid that!) or denim jacket and wear with a stripey tee. 
Recreate Sam's look (kind of):
Chaser suede collarless leather jacket, Vero Moda suede biker jacket, Topshop suede fringe biker jacket, Acne Studios Suede Velocite oversized moto jacket, or Doma suede moto jacket
Saint Laurent Classic crew neck striped tee
