It might just be the picture, but it looks like if anything the tie washes out a little too much relative to the shirt.
Personally I would not ask a bunch of Linux nerds for fashion advice
I have no male fashion hobby or interest, but as a layman lurker from /new, I think it looks great.
Also not a regular here, but my first impression is that the gray is an issue here. I think that the pink and the gray would work well, especially with other cooler tones, or lean in on the warm brown with the pink instead (maybe with a dark brown vest?).
It’s impossible to give advice on color if the lighting was bad for the picture.
To be honest, all the colors look completely off to me.
But I can’t tell if it’s my screen, your screen while you white-balanced the image, the lighting or the actual color of the clothes.
It took me too long to find the pink.
Imo the tie and shirt do work together, but they’re both quite light and washed-out, so the waistcoat being much darker than both prevents the tie from popping out the way it should. To rephrase : if I squint, I can’t really make out the tie from the shirt compared to the waistcoat.
Changing just one thing, a rich/dark red tie or perhaps a lighter waistcoat might work well here.
Otherwise I think you’re pretty fly :)
