It’s a great kind of jacket to wear when the sun is out in the winter, but should we wear it Smart Casual or with a suit? Suitsupply has some new bodywarmer jackets that are a 100% wool, so they’re pretty snug. I personally think it looks pretty weird to wear a bodywarmer jacket over your suit jacket, as the suit jacket will pop-out underneath your bodywarmer. You should only wear it over your woolsweater or pullover with a Smart Casual style. Check out the photos and answer the following question: Hot or Not?
