Mm, not sure that particular shade of blue works.

I see your posts a lot but never comment, so here’s some suggestions to try out:

Learn to pair different knots with different ties. Asymmetrical knots don’t always work with certain sizes. Experiment with making the knots tighter to give more definition. This tie would look better with both a symmetrical knot and a tighter knot.

Periwinkle works like gray and gray doesn’t pair with either of the other two colors well. The vest itself is giving you clues with its own pattern.

Your shirt shouldn’t be the same shade and color as your pants. This gives a mismatched uniform look if the colors don’t match exactly. If you want the same color shirt and pants combo, go with shades.

Don’t make everything in the ensemble a color. Neutrals are there for balance and will help your accents pop. All pieces here are screaming for dominance.

Next time you press your pants, stop the crease at the bottom of the pocket. This prevents the illusion of pleats and also prevents the pants from wearing too much.

In my opinion, you could fix this entire outfit with a white shirt.

What's with the crescent chains you seem to pair everything with? Is it a cultural thing?

Looks like you are supporting a sports team but I don't know which one.

Pleated pants need to go to an island and die.
