I hate chef formal dress. This is where chefs wear a chefcoat over a shirt and tie. Compare this to a regular suit and tie and chef formal looks downright ratty. The chefcoat always wrinkles, especially in the back, the sleeves are never the right length, the collar never sits right, and the buttons are never really nice and tight.
I say junk this method of dressing and adopt something more respectable.
Yeah I agree those guys that show up on Iron Chef (only experience I can relate too) with a tie under thier jacket. What is that man look serious for cooking, and look serious for formal. Both at the same time doesnt work.
