I’m wearing a Medium. It's currently on sale for $70. Original price was $155. Club Monaco sweaters will last you several seasons. You get what you pay for. The sweater with a lighter color linked below is top ranked on the Anthropologie website. It too has an interesting neckline. They both are what I like to call perfect for dinner pieces, where your outfit only shows from the waist up.
My first pair of green pants were purchased in Houston, a pair of chinos from Anthropologie. I had gained a little bit of weight so my jeans and my dress slacks weren't comfortable anymore. I kept those green chinos for 4 years. Not bad. Heaven only knows how many times I wore them. They match with more outfits than you would think. You can wear them with white shoes, black shoes, tan. If you don't already own a pair of olive green pants, I would suggest adding at least one pair. The color can be worn year round and you'll get so much use out of them. The pair I have now were found here in Dallas, on the sale rack at Neiman Marcus. I plan on keeping them for a long time.
Most of my friends own either black or brown boots. Gray is always a great alternative.
