Don't throw away that Tuxedo Shirt. They cost a lot but there is life for that old Tux shirt anyway. So, don't toss it to Goodwill.
Instead take it to a tailor & have the short fly collar taken off & re-seamed, making a one inch collar band that stand up. It makes for a great Nauru, Mandarin or Quaker style shirt for a great look with jeans. Especially if you have a thick neck like I do, the stand up 1" collar band makes for a slight camouflage of that thickness & gives you a svelte look in Wranglers or the slacks of your choice.
Don't button the top two buttons. It's OK to show some Fur. We own it, we've earned it & men love it.. Or if you do choose to button them, they sell a button cover at Tux shops that will match any mood, from black or silver to a nice gem stone.
I prefer Wranglers jeans with this look, cause Wrangler Butts drive me Nuts. I can only hope for the same reaction.
Party On...
& Growl the night away cause they'll be lookin at you studs.
