Comfortable and breathable

Really cute dress to wear for fall, it’s so comfy … feels like I’m wearing a blanket. However the dress is absolutely beautiful!

TEAM RTR REVIEW

The knit fabric is incredibly comfortable and cozy, making it perfect for the fall months ahead. The bell sleeves are a super cute detail that makes it feel chic and feminine. The fit is body-hugging, which lays nicely, but I'd recommend sizing up if you are looking for a bit more forgiveness in the midsection.

Tall friendly

This was a great dress! Styled for work and weekend. Fits tight, I’m typically a 4-6 and 8 fit great.

Comfy, stretchy dress

Ended up not wearing this dress because the weather was warmer than expected, this is definitely a fall/winter dress. The fabric was very stretchy, the type of dress that should not be hung up. It arrived NWT, you can see in the photo that it was slightly stretched in the chest area, I would want to wear with a black bra. Maybe I will try again in the winter.

Lint and static magnet

The fabric is chunkier than I expected. It was covered in hair immediately. The way the model has it styled would be cute but the weather wasn’t cool enough for me to wear it like that yet. It was OK and comfortable but just not very flattering or exciting.

Soft & Stretchy, But Sheer

Long black dress that’s soft, stretchy, and comfortable. Unfortunately it’s fully see-through, so you’ll need your own slip to wear it. I don’t love wearing slips, so it was a no-go for me. Would work if you have the right layering piece, but not for me.

Really cute fit and I like the material it’s different than a sweater

It lays really well on your curves

Cozy and soft

Accidentally got size 10 when I’m a size 4 normally, still wearing out as it fits tighter, I would’ve probably picked size 4 for fitted fit or 6 for loose fit. I’m petite and it fit well.

Really nice!

This dress is super cute but runs a touch big. Very stretchy and very warm!! Moderately see through when stretched, but I threw on a tank and boy shorts under it and was comfortable wearing it to work.

Belt it!

Fabric is great. Dress is long but I am tall enough it worked for me. It’s a dress up not down kinda style. Added an animal print belt and booties. Great dress!

It just feels a little too mature for me

Okay-I really wanted to love love this dress. I tried it on and it was reminded me of something my 70 year old mom would wear. It would look lovely on her-but definitely not the vibe that was found for. The fabric is super lightweight. It just looked really silly on me especially with the awkward collar. I’m sure this might be a love for someone. It just wasn’t my style at all. It feels like it was straight out of Talbots.

Sheer, scratchy synthetic

This is very stretchy and hangs awkwardly on the body. The material is very scratchy knit synthetic and is completely sheer and requires another dress underneath. I expected this to be a warm cozy sweater dress, but it is not remotely insulating due to the synthetic material and open weave.
