Team RTR review

Love this super casual dress. Comfortable, perfect work from home dress. Runs a bit large, but that is fine. This was NWT so it felt a bit stiff, and the neckline was a tiny bit higher than I would like, but honestly, I still loved it. The color is gorgeous!

Comfy Cute

I loved this! I wore it once with boots and the other with tennis shoes. I received it with the tags on, so it's brand new! I do wish I would have sized down for a more snug fit though. It was a tad too big.

Lightweight and comfy, snug in the right places

I absolutely love everything Hill House, especially as a person in my first trimester of pregnancy. This dress is comfortable, and you can wear with or without a bra. I wore one since I wore this to work, but not necessary especially if you have a smaller chest.

Wore a million times

A medium may have fit a tad better but I did like that the large was loose so I never felt constrained. I could wear a regular bra which is always a plus for me. Great to wear for a multitude of occasions. Loved it!

Earns its name

This dress is truly comfortable and easy to wear and the print is very pretty. It's blouses out too much for my taste around the belly and made me look a bit larger than I would like. I suggest sizing down. While it can be dressed up I think this dress is best for a lazy weekend or coffee run

Not my favorite from hill house

Loved the neckline and smocked top part but this dress had more fabric than other hill house dresses below the smocking or something. Created a weird bubble bump in the back/behind area and the dress was sort of coming into itself and tripping me when walking in even mild wind

Love the color and fabric

I absolutely love this dress and wore it a few times but I will say it did make me look like I was expecting even with shapewear. It’s super cute and comfortable so if you are fuller in the mid section just be aware.

Bump Friendly

Have seen a lot of girls rock this style while pregnant and it works very well with the bump. Only complaint is I wish it was a bit more midi - it hits a little too long for me to wear sneakers with which I love to pair dresses with. All in all, would rent. Received lots of compliments.

Too long

Don’t love the pattern. The other HHH nap dress shrunk when I washed it, after I hemmed it, so I got the larger size this time. Dont think I’ll buy this one because I don’t like it enough to go through the hassle and expense of getting it hemmed. Pockets ✅

Maternity Dress Only

I sized down hoping to avoid the poof issues others experienced, but I still looked pregnant. Something about the high waist with the flowy skirt just doesn’t sit right. I returned immediately

Gorgeous but not nursing friendly

The classic nap dress styles are more "nursing" friendly than this style. Also I found it's tighter on my chest than the classic nap style, as well. Gorgeous print though! Will rent again when not nursing :)

This dress was super comfortable and easy to wear. It's a nice shape and fits in all the right places so you don't need to adjust it or worry about wardrobe malfunctions while you go about your day. I wore it parenting and to visit family, and it was really fantastic. Highly recommend.

The perfect dress!!!!

I own a Cosima nap dress and grab for it constantly. I'm so glad RTR picked these up so I can wear different colors/patterns without having to buy so many $200 dresses! Perfect for work or can be dressed up. Truly sooo comfy and flattering as a pear shaped girl.

Long and lightweight

New with tags and almost kept it. I'm petite and this went down to my ankles. But I loved it. So easy to just throw on and wear alone or with a jacket. Wore it with sneakers and sandals. It's cotton so very breathable. Fitted in the top portion but conforms to your body. Loved the higher neckline. Wore it for work, to a concert and general running around. Will definitely check out more from this brand.
