Wear with tights xoxo

Fit a little big in the waist, but was still super chic. On the shorter side, but looks amazing with tights.

Versatile LBD

Fit was slightly large- the sweater material the top half is made with would stretch somewhat after wearing but I wouldn't size down intentionally unless you want the dress to be even shorter. Great layering piece or worn alone.

Cute winter LBD

Loved the look of this dress! The gold chains were a nice little detail. It was comfy and fit well. I don't have much of a defined waist so it might be big for someone that has an hourglass figure. I could also see that it might a little short for taller women.

I wore this dress for a night out and it was so comfortable. Definitely flattering and stretchy and kept me warm. Definitely a chic dress to wear for a nice dinner or date night.

Chic!

Love this dress, but I think I would size up. I’m 5’6” and felt that it was short at the torso & sleeves. Very slimming, super chic. Would have bought if it was a bigger size.

Team RTR Review

The cutest two for one dress! This dress features a knit sweater top with a woven pleated bottom for a feminine & flirty but clean look. The skirt is definitely a mini, so if you're on the taller side you may want to size up. Otherwise everything felt true to size and oh so comfortable. I would definitely pair this with some cute tights and a heel for drinks with friends!

Nice fit

I usually don't like dresses that poof out at the hips making you look wider, but this one was very flattering and comfortable. Wore it to work and to a funeral.

Easy go-to winter dress, but a little frumpy

I rented this to wear over the holidays at home & for work events but found I would always choose another outfit over it. While it was so cute on the hanger, I felt like it actually made me look a bit short & stout when I put it on. The length & the fact that the thick materials doesn't really suck you in, I think contributed to that. Maybe it's meant for someone taller... it's only a 6/10 as I want to like it so badly, but I didn't like it on me

Cute details with chains but nothing special!

This was a cute work outfit. Ended up wearing to a work dinner with tights and heels. It seemed like there was extra fabric on the skirt part when in person. The length was fine without tights, but i decided to wear some bc it was colder. Cute enough dress for work!

Short, baggy, cute

This was a super interesting piece and lots of people commented on it. I think it was too short for work and it was really baggy around the waist. Almost like a babydoll dress. But the chain details were awesome.

Couldn't wait to take it off

I don't know why but top half wasn't comfortable. Not necessarily itchy but just irritating. The fit was fine. It's a tad short. I wish the way it felt on my skin wasn't so annoying.

Paired this a couple times with black tights and boots. Wore on a date and out with friends can be worn in casual to dressy casual settings. Always received compliments when wearing. Hugs nicely but is not at all tight.

Beautiful!

I did NOT want to return this beautiful piece. Great adornments. It runs a little big and it was difficult to know if it faltered my shape because it was not hugging my curves enough. I'd like to know if the smaller size would look better.
