You can argue about it all day, but the people who wear suits and understand the most basic of "rules", know not to button the bottom button.
And for the record, I would guess that more people agree to leaving the bottom...
I like your mad sport coats. Sometimes though, the top can look relatively conservative, while sporting it with green trousers etc, which doesn't really fit together.
Never throw out any of your Tom Ford gear, you can pull them off.
