I have a jacket that is this same in-between length, Aida, and I wear it with my jeans, (even since YLF). It's navy, so it sort of creates a column of colour effect (I hope) and I actually really like belts showing, so when that happens it doesn't bother me. I'll post my self-education post as soon as I'm able to get the pics.

Oy! I swoon! Those shoes are pushing all my buttons in the very best way imaginable!!!

I love a short jacket so this whole look gets an A-plus from me!

I really love this outfit...I have a weakness for anything tweedy The length of the jacket doesn't bother me at all, I actually prefer it with the shirt tucked.

If it still bothers you, I might try it with jeans/slacks that have a slightly higher waist. I have a few cropped jackets like this and I find the higher the waist, the better I like it.

Thank you ladies for all the great and insightful comments! They were super helpful. Seems this "in-between" jacket length is a bit subjective, but I am still pleased with how it turned out (and glad I'm not alone on an island with that opinion). So I will just be mindful of what pants I pair this jacket with and if something feels off, likely it can be solved with higher waisted pants
