I have this style sweater in several colours (4)and love the fit, styling and versatility, however, I ordered the "lawn green" colour, the fibers of this particular colour shed on everything it comes into contact with. I like the colour, but have to return the sweater as it's a nuisance to wear! Beware the "LAWN GREEN"!
The fit is generous enough to allow a warm long-sleeved shirt under it, but is not bulky, in fact, it is flattering. I think the fit is true to size. Sweater has an interesting stitch and is very warm. I had owned one before and lost it, so I quickly bought another!
I purchased this sweater as a Christmas gift for my SIL and it was perfect. I don't understand the bad reviews of it being so light weight because it is not.. We live in NW PA and it gets very cold here. She was thrilled and the fit could not be better.
