This time of year is all about heavy knitwear.

If you’re looking for a sharp but approachable “business casual” look,  swap out your suit jacket for a chunky sweater.

Not only will it keep you warm and comfortable, but it offers an appealing contrast against the rigid lines of a business look.

Here’s three examples for your Fall commute.

1. Knit Peacoat

A navy peacoat is an everyday essential in a man’s Fall/Winter wardrobe, as we discussed in our article “Re-Invent Your Wardrobe with 25 Essentials“.

This time of year, however, it’s too warm for a heavy wool coat.

Look for a lightweight knit peacoat, which is essentially a cross between a double-breasted cardigan and a classic military coat.

Treat it as outerwear and take it off in the office, unless you work in one of those buildings that keeps it brisk all year with heavy air conditioning.

Of course, when it gets colder, you can wear it as a sweater, layered under a heavier jacket.

Tips for wearing a tie bar:

- It should be worn around the sternum, just below the chest muscles.

- It should be the same width, or slightly narrower than the tie. Never wider.

- Sounds simple, but it’s purpose it to fasten the tie in place to the shirt! No floaters.

- Lift the top of your tie slightly before attaching it, creating depth with a subtle “bow” above the bar. To accommodate for this, you might want to fasten your tie a touch on the longer side.

- Don’t wear it with a waistcoat, cardigan or sweater vest – these already hold your tie in place.
