Great cardigan!

Good quality cardigan. Heavyish weight despite the sort of mesh design. I loved it. A small worked well.

Great color and comfort

This cardigan is weighted so it fits well, is comfy, and stylish. It fits true to size but if you are between size down. I enjoyed wearing it layered.

Great Sweater!

I loved this sweater. It was comfortable and warm for a day in the office in the wintertime. I'm often cold in the office but not with this. It sits in a really relaxed fit and has a heavy feel to it.

Loved!

I loved this cardigan. It was warm and perfect to wear to work and the library. I thought it was going to be colder because it has holes in it, but it was a thicker heavier material. It fit well and was a cute color

Fine 😐

The color and weave of this sweater feel expensive, but the cut and style of it are rather plain. I didn’t find the bottom band flattering and even though it’s an open weave, it’s almost too warm to wear indoors. I’d say don’t bother.

Fall sweater

Sweater isn’t itchy but not the lux softness that I love (ie Barefoot Dreams). In the picture the light is coming thru the loose knit and I wore it with a cami underneath. If I was buying, I might size down.

Beautiful Color

Order your true size even if you’re going for a baggy look. This sweater has lots of room. It was a nice weight for a cooler spring day. Could dress it up or down.

Cute but heavy!

Wore this several times while I had it, and loved how it looked. The sweater is pretty heavy even on the hanger, but didn’t make me overheat since it’s kind of mesh-like. Would rent again!

Very heavy

Didn’t end up wearing this sweater beyond trying it on with several possible outfits. It was very heavy and the texture just felt off. I usually have great luck with Jason Wu pieces here, but this one was a big miss.

So pretty!

Fits tts, have a larger chest (especially post partum) and was able to button it up easily. Hangs well. Is heavy and decently warm considering the open weave

Far more sturdy than expected. Wore on work calls and around the house. In the summer but I get cold in the AC. Wanted to buy it but too expensive. Hope to at least rent again.

Great cardigan

The color is on trend and it’s substantial without being too warm. It’s not a soft and fuzzy knit, but a firmer yarn. Liked it so much I bought it

Versatile and high quality

Loved this, almost bought it. Cool to the touch but it keeps you warm. Cute fit if you don't mind a small poof above the waist when buttoned. A favorite color, so I wore it with everything. One of my favorite sweater rentals.

Hangs well, heavier weight sweater

Loved this sweater. Definitely on the heavier weighted side, but the knitting is somewhat open so didn’t make me too hot (just warm enough). It hangs really well (doesn’t make you look too bulky) and got lots of compliments!
