Perfect sweater with pretty sleeves

Nothing overly special about this sweater but I got compliments every time I wore it. Nice quality and weight, I could have kept this one.

Great go to sweater!

Super cute! Wore for gameday! Nothing really special about it but it fit well. I wear a size 6 and got a L because it’s a sweater and it fit well on my lanky build!

Cute Sweater

The slight puff sleeve is a cute detail. Nice purple color. It’s thick so I wouldn’t keep this sweater but I wore it twice on casual work days with jeans.

Cute top but very cropped

Cute sweater. I liked the purple color and puff sleeve detail but this sweater was VERY cropped and felt a bit short for me. I have a slightly longer torso so maybe just an issue for my body type but worth noting. Wore with high waisted jeans and a camisole underneath tucked in as it rides up when you move your arms.

Nice, definite shoulder puff

Nice color and weave of the fabric. The sleeve puff was a touch dramatic but not too bad. Would probably rent again.

Great color!

This sweater is cropped. Great with high waisted pants. Sweater wasn’t itchy but wasn’t soft. It was a heavier thick sweater.

Didn’t love.

I felt this ran on the smaller side. Didn’t love the fit. Didn’t think it was that flattering.

Cozy and stylish sweater

This item is both comfortable and has a nice silhouette. The sleeves are a bit more defined than you can tell in the picture but not too puffy! It was a very flattering fit as well.
