Size down

This is the second time I’ve rented this sweater. It was a little big the first time so I sized down and it was perfect. Love the leather button detail and puff sleeves.

The cutest puffy sleeves

I really liked the fit of this sweater. The sleeves were just puffy enough to give it the cutest vibe! It can be worn with jeans or any type of pants.

Elevated neutral sweater can be dressed up or down

I love this sweater - I rented it twice and wore it quite a bit both times. Works with jeans or elevate it with slacks or a skirt.

Better than I thought!

A little outside my normal style and a great mid up. Heavier/chunkier than I expected but great for mid-spring weather.

So cute!

Have worn this sweater the last 3 days in a row. It’s comfy but cute enough to look like you were intentional with your outfit. I am normally S or M and went with Small this time, it fits perfectly. Wearing with my RTR black Levi’s - love the look!

Loved it

This is a great sweater. It’s a little cropped and a little loose but not too much of either and just very easy to wear. Super soft and comfortable, I usually refuse to wear any synthetic fabric knits but this one is making me reconsider as long as it’s at least 50 percent wool. I love an off-white and the tiny flecks of multicolor in it was just enough.

OBSESSED

This sweater is SO cute and easy to dress up or down. I’m normally a medium or large and glad I went with the large for little bit of a looser fit. I’ll definitely be purchasing this!

Cute top

I wore this to work with a shirt under it because it’s a little low cut, but casually I would actually style without the white tshirt under. The material is thick and a little scratchy—it’s definitely more of a fall sweater than a spring one.

Cute

Cute, casual silhouette. Great length…not too cropped. Beautiful hints of color through sweater. Heavy cable knit so appropriate for fall or spring in colder climates.

Adorable everyday wear

I wore this for work and out to dinner. Casual yet elevated. A little thick and a bit scratchy, but still comfortable for me. A bit big in the chest and the button is a bit low if you have a short torso, so I had to hold it when I leaned over.

Looks put together

Sweater makes easy quick "put together" look with flare jeans, belt and booties. Got unexpected compliments thinking I was just throwing on a sweater. Slightly cropped so looks best with a belt which will show. Also don't get fooled by short sleeves - sweater is warm. First time I wore it I was overheating because it was more of a warm fall evening. Waited to wear it again once it got cooler. Would rent again next fall.

Cute & warm

I liked throwing this on over light shirts as the weather changes. Got a few compliments as well. Some might think it's scratchy, but I didn't have any issue wearing it over sleeveless dress all day.
