There is an age-bias involved, but button the top button and snug-up the tie.
A tie worth wearing is worth wearing correctly.
The picture looks like a good start. Just so you know, it's a little too dark to get a call on the colors, you might open the blinds to get a little natural light in to help. Also if you can you might want to include your shoes so we can tell you if you are making any faux pas.
Yes this is an excellent start! Looks dressy yet relaxed.
Ok, I replaced the buttons to look less "navy uniform"
That's a shame. I liked the brass buttons. Whichever you prefer though, it looks good either way.
They were a silver color. I didn't like them. Too "prep school" or "navy uniform" look.
