Kerry, so great for you to provide us with prices. That's really helpful.
Based on what you are saying, I think you should keep the Kut jacket for sure. It's easy to shorten sleeves.
I sympathize about the leggings. Every year at this time I try a pair. Last year I got a pair that were leather look on the sides only and regular leggings elsewhere...they are the best leggings I've ever had and I still don't like them on me. I get the sausage casing look.
Re the sweaters...sad to say, no knits hold up to a lot of wear...or at least not anymore, in my experience. However, some are obviously better than others. I can't predict whether the Burberry sweater would last longer but if the fit is not good, hold out for one that fits as you'd like. Meanwhile, the Halogen one is quite interesting and unique with the stripe and could be useful, too, it seems to me.
Nice reviews -- thank you!
