I ended up putting 3 looks together for different occasions, this is them:
Casual:
Simple Black pumps, with a basic black T-shirt or jumper (also add a pop of colour, with a red scarf or accessories)
Smart:
White shirt and brogues (add a blazer for a super smart interview look)
Party:
Add some colour with a basic silky vest and matching heels!
It was actually quite easy, I always found print to be a bit daunting but thinking about it, as long as everything else is minimal, it works!
