Warm, Versatile and On Trend!

I borrowed this for the winter. Living in a warmer climate, I only have me even item like this about a month or two out of the year, so this was absolutely the perfect solution! I wore it with a lightweight top anytime the temperature dipped below 50 and also took it with me while traveling over the holidays, where I layered with warmer tops when the temps plunged to below freezing. I'm definitely considering purchasing this one!

Very flattering cardigan

I didn’t realize a cardigan could be so flattering! I really really loved it and I was going to buy it to keep but saw it had a little pull so I changed my mind. Very soft, not itchy.

Solid sweater

I liked this but I didn’t love it. It’s nicely warm, cut well, not itchy and not too cropped. I like my clothes more oversized. I enjoyed it

Statement and versatile

Love this. Looks great with jeans and also wore with leather skirt. Soft and warm but not too heavy. Sleeves are long enough for me (I have pretty long arms) and it drapes beautifully. Will probably buy!

Interesting version of Fair Isle

This cardigan caught my eye because the diagonal placement of the pattern looks more interesting than a traditional Fair Isle cardigan. The blue and gray colors are very versatile. The fit is large; I sized down to small instead of my regular medium per RTR recommendation, and it was still boxy and not very flattering. When buttoned, it was too low-cut to wear without a shirt. I didn’t find it itchy as some reviewers did, but it wasn’t particularly soft.

May not be very flattering because it's oversized and boxy but that's the style. It was comfortable to wear and warm enough for a Texas winter day (50s).

Casual Cardigan

Everyday cardigan made of tight-knit fabric that isn't itchy. Sleeves were a little long and felt tight because the fabric doesn't stretch. Loved the slanted geometric pattern for elevating basic tees. Will rent again.

Beautiful sweater, great fit

I think I'm keeping this. It's not too heavy, not too light. Warm without being binding or uncomfortable. It's well made, nice colors of light gray and blue. Can wear with jeans, but it is nice enough to wear to work (even though I'm retired I would have worn it to work).
