Men's button-down cardigan patterns

Greetings-Last Friday night Tom Selleck on Blue Bloods was wearing a cream colored cardigan with a narrow shawl collar and it “V” neck line to big wooden buttons going down the front. My husband backed up the show 3 times so that I could take a good look at the sweater, LOL! And pronounced that was the exact sweater he would like me to make for him. HELP! Where can I find a pattern to make that sweater? I would like it to be bottom-up if possible. Anxiously awaiting your replies! Thank you. P.S. I’ve been all over the internet and haven’t been able to find exactly what I’m looking for.

You may have to join Ravelry to see some of these (it’s free).
