It's often a nod to, rather than full on.
So, I basically take a look i like- like 70s tv presenter or Lois Lane, and go from there. That could be wide brown trousers and a mad, pointy collar shirt. Brown boots. Currently loving that tank tops are around.
Or 60s Beatnik- black polo neck jumper. Short skirt. All the eyeliner, but less than in my 20s.
Katherine Hepburn- wide trousers, high waist, flowing shirts.
Then there's the odd nod to my goth youth.
I grew up in the 80s, so i try to avoid that, because it's princess di and my mum. Although i guess pleated skirt/tshirt/ flats is very much what my mum wore.
I was very Madmen inspired in my 20s, but that was easy because so were the shops!
I would never have survived in a job where I had to wear a uniform. I disappoint myself when it's just a boring shirt and trousers day.
