What colour cardi with a navy dress?

[pinkfrocks]

I have few smart summer dresses and they are all navy
I am hoping to maybe pick up a cardi in the sales to wear on cooler days ( sleeveless dresses) but what colour?
I was thinking of camel or grey. I am fair skinned and have fair slightly strawberry blonde hair.
I don't want white or a harsh colour like red/ orange.

Ignore me, I forgot to read your final line!

navy and mustard is lovely together

I'm into navy and mustard at the moment.

Teal's nice all year round, cream/oatmeal shades are good too.
