Black tie advice

[Mr Tickle]

If going to a black tie event , is it ok to wear a dark blue dinner jacket with black trousers? Or would it always be worn with matching blue trousers?
I've read a few articles looking for advice and what I have found is a bit contradictory. Some say jacket and trousers should always match (down to material and matching lapel/trouser trim.)
Some say "odd" jacket and trousers are fine so long as the trousers are black and tailored.
I've even been staring at pictures of Daniel Craig as James Bond in a dark blue DJ, but my eyes aren't good enough to work out if the trousers he is wearing are black or very very very dark blue.
If so, what would the right trousers be? I assume I wouldn't want to simply throw on an orphaned pair of black suit trousers. Or my existing black tuxedo trousers which go with my black tux. Is there a particular style of dress trousers I should be looking for?

Only asking because I've seen a very nice looking midnight blue dinner jacket for a very tempting price, but it doesn't have matching trousers.The old tux is looking a little tired but it would probably be good for one more outing if the blue DJ is not a good option.

blue dinner jacket plus black tuxedo pants is the way to go

Blue jacket will work provided it has the right features and isn't notch lapel

You should take a look at the State of Black Tie thread. A quick search shows mixed opinions on this pairing.

Some shades of blue can definitely work very well for an odd dinner jacket but midnight is too close to black. Craig’s suit had matching midnight trousers (as did Connery’s, Cary Grant’s, etc.)

Sadly, this is true. Midnight blue does need matching midnight blue trousers. For a long time, I believed otherwise until I bought some midnight blue mohair cloth. I realized then that I needed to make a full suit or it wouldn't work. Almost any other color blue will work, though, even navy blue.

If the jacket you're looking at is not part of a suit, my guess is that it is not a true midnight blue. Maybe take your dress trousers with you and try the jacket on with the trousers? That will tell you quickly enough if the jacket will work with black trousers.
