Also, what colour shoes with navy pants? - I usually wear black. Brown doesn't work and nude seems to stand out and is really hard to find anyway. I work in an industry where red shoes would probably not work.
I hope you can make sense of this hotch-potch of stuff!
Many thanks

How to Mix Navies
The key to mixing different shades of navy is to find ones that have some similarity particularly in undertone and also intensity. Some are brighter and more intense, others are softer and more greyed down. Some are warmer marine navies, others are cooler more violet navies.
You can mix some different navies, but the do need to relate to each other. Similar intensity and undertone will help to make them work together.
Different textures also helps, so a knit with a woven fabric we know they are not supposed to be a 'suit', but jacket and pants that are not a suit are harder to mix. Above I've mixed the navy denim, with navy pinstripe jacket and sheer navy top - all different navies but they work together as there is enough similarity, yet we know they are not supposed to be exactly the same as they are not part of a suit.
Using patterns can also make it easier to mix them, a linking piece with a pattern that includes navy will help you mix them more easily (and it will make it less noticeable)
Both navy pieces here are blue and white which creates the harmony.
Which Shoes to Match with Your Navy Pants
As far as shoes to go with your navy pants
Black, deep brown and of course navy are all great if you want leg elongation and a column of colour.
If you want to make more of a statement try oxblood or came (camel is great if you are a blonde as it creates lovely visual grouping too)
