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.

High quality, pretty pattern

I’m 35w pregnant and 170 lbs (normally 140). I probably should have done the L but the M was fine and stretched. High quality, comfy, loved that I didn’t have to worry about the straps at the top, they’re thick. Great dress!

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

Comfy summer dress with pockets!

This was just a nice, simple dress that would look good on any body size. It's a soft cotton with a nice elastic style bidic and big, deep pockets. Not going to change your life, but will be comfortable to wear during your beach vacation.

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 :)
