If you are looking to change it up a bit, and you find your blue OCBDs a little boring, then try a plaid shirt under your tweed jacket. Personally, I find it to be a nice look, but picking the proper tie can be tricky. I find that one has three choices:
1)Solid Color Tie 2)Solid Color Club Tie 3)Yellow Foulard Bow Tie
So, the next time you feel like adding some excitement to your day, try a plaid shirt under your tweed jacket.
