How to Match Dark Colored Jeans with a Shirt | Tips on Color Combination

Question from A:

When wearing plain dark jeans, is it better to match light colored tops or dark colored tops, or can you do both?

I am having trouble color matching rules; is it dark on dark better or dark on light and vice versa.

I realize it depends on the pattern and color, but to make it simple, would i match dark colored jeans with a light colored polo or a dark colored polo.

Also, with wearing light colored jeans do the same rules apply? (Light colored jeans on dark shirts or light shirts).

Black suit, dark blue shirt and a tie?

Hey gentlemen!

I have a question for you. I recently bought a dark blue French cuff dress shirt which I really like. So my question is, when I wear a black suit and that same dark blue dress shirt, what kind of tie can I wear?
And I don’t mean only what color but also neck/bow.
I slightly prefer a bow tie but if that just doesn’t cut it I’m fine with a neck tie as well. One more thing is that I’m not going to wear it for work or anything like that. I’m young (15) and only wear a suit when I either play trumpet in a concert or go to theater etc.
Well I hope you understand what I mean and can answer it too!

Best wishes,
Jüri

What Are Acceptable Shirt Colors for a Navy Blazer?

For a relatively formal (business) environment, what would be some good shirt colors to wear under a navy blazer paired with grey trousers?

Of course, I know white is a good color, but what else works? Are darker shades (purple, blue) off-limits?

Looking at some of the following linked shirts, they seem fine on their own, but imagining them paired with a navy blazer makes me doubt their acceptability.
