Spring is one of the trickets times of the year, because on any given day the weather can go from comfortable patio weather to sub-zero. So, how does one prepare for weather so unpredictable?! Aside from owning some great outerwear pieces, sweaters are a definite must-have during this season. For those colder days you can layer them with t-shirts and dress shirts and for those warmer days you can just simply wear them on their own. Nothing is quite as versatile as a great sweater in your wardrobe. Here are some great colourful examples from Stones, Zanerobe and John Varvatos.
