Not actually today but yesterday:
That's cool. We have different tastes. Glad you like the jacket and pants.
My thinking goes along the lines of my gut feel as soon as I see myself in the mirror. If nothing feels to be off then I go with it. There have been times where individual pieces worked in theory but looked off to me in the mirror. I'd wear them anyway it would be rightly called out on it.
These days, I tend to go with my gut instinct and it's worked out more often than not.
The rationale behind the combination here was that I chose the shirt and pants first and wanted a blue jacket that contrasted with both but was still darker than the pants. A medium faded denim jacket might have worked but this jacket was the closest I had to that particular shade so it got picked.
At the end of the day though, it's one days worth of clothes and if it doesn't work, so be it. Tomorrow, we start again
@pravda, thank you for the kind words.
