This is very flattering and cozy for winter. Super flattering and great for cold days. Would've worn it more if it stayed colder longer here!

Team RTR Review

Such a flattering silhouette! The v-neck is pretty low cut which is perfect for a date night, however, if you want to wear to work I would recommend wearing a cami underneath. The material is heavy weight and stretchy making it a comfortable fit. The buttons are functional and runs true to size!

Just barely too small

The way it was too small made it bunch up at each button. But I did like the color and how it accentuated an hourglass figure!

Peplum fit is great for hourglass/wide hips

This ended up being a great cardigan for my trip to Rome. I paired it with the Ulla Johnson Vitorria Dress. I probably could have sized up to XXL if it had been in stock, but it worked. Fabulous for cinching my waist. It was thick and kept me warm when the nights dropped into the 40's. Only complaint is travel realted: it was heavy and didn't compress, so it took up significant weight and room in my luggage.

Thick sweater, versatile…

It’s thick! It’s warm. Cozy, comfy. Good for a work outfit or with jeans for a casual day out. I guess it could be worn without something under it, but may have a little ‘itch’ factor to deal with. I’m sensitive to itchiness, so wore with a blouse as if it were a jacket/blazer. I’m @dawnpriscilla on Instagram for more pictures/reviews.

Peplum is back baby!!

I cannot believe peplum is back, but here I am, and the high schooler in my heart is so thrilled. This really accentuates your figure and waistline and has an English riding vibe to it that elevates an outfit. 10/10, would peplum again.

Beautiful Color & Shape, But Material is Itchy

The color on this cardigan is beautiful — a deep, rich burgundy that looks great in person and feels polished for work. It’s also warm and structured, with a flattering peplum shape that gives definition at the waist. That said, the material is on the itchy side, which made it a little uncomfortable for all-day wear. I layered it over a top, which helped, but the texture is definitely something to be aware of if you have sensitive skin. Overall, it’s stylish and cozy-looking, but comfort was a drawback for me.

So feminine and warm

Creates an hourglass shape and looks adorable. It was tight when I buttoned it though so it runs a bit small imo.

Sexier than it appears!

Has a much lower neckline than it looks online. I couldn't wear it to a work event without having something under it! Wore it out for a girls dinner and got tons of compliments!

Beautiful sweater but the v neck may be lower than you're expecting

The color and quality of this sweater were both above expectations. My only critique is that the sweater showed more cleavage than I was expecting. I was able to use double sided tape to make it work appropriate. Will rent again!

Heavy and cute!

I'm between a M and L and rented the M. There is some stretch. I wore this multiple times - to work and casually. Awesome piece! Heavy and perfect for winter but not your typical cardigan or turtleneck. Loved it!
