I know I said I don’t like bright colours…. there are always exceptions though!
Provided the rest of one’s outfit is extremely simple, one doesn’t invest too much money and does it with summer clothing….one may want to consider something really bright. Like these:

Zara buttoned blazer bright blue

Zara buttoned blazer bright pink

Zara buttoned blazer mint green

and if you think it’s a bit early for the above, which I completely agree with, there’s always a nice bright mid-season coat…

Zara wool coat green
