Loved!

This was such a cute dress and fit was true to size pre-maternity. I was comfy all night as it's stretchy. It's not to be worn in hot temperatures but Texas was not cold for Christmas and I was comfy. I felt great and got lots of compliments!

Sleek, versatile, and chic—perfect day-to-night dress

This was such a sleek and versatile piece—polished but still very comfortable. The collared neckline with the partial button front makes it feel a little more elevated than a basic black dress, and the ribbed knit has just enough stretch to flatter without being restrictive (I’m about 5 months pregnant here and it worked really well). The length hits right below the knee, which looked great with ankle boots, but it would pair just as easily with heels for a dressier vibe. It’s form-fitting but not overly tight, and the fabric has a nice weight to it. A perfect choice for work events, dinners, or anything where you want to look chic but still feel at ease.

27-28 weeks pregnant. Gave Rachel Green vibes lol

I think sizing up in this one might have been a good idea but on the fence. It was very bump hugging and the buttons would pop open some. Cute style though and like I said made me think of something Rachel Green would have worn pregnant :)

Wore 26 weeks pregnant

Very comfy. A little thin, but I wore pregnancy shape wear to smooth everything out. I have never had boobs before pregnancy and noticed the buttons pull a little on the top. If you are busty you will have to wear it all the way unbuttoned and/or wear a top underneath.

I wore this a few times at 35 weeks pregnant - easy to dress up or down. Flattering silhouette and the collar/neckline was really pretty.

Great for work events

I felt great wearing this for a work conference, professional and flattering. I'm in my second trimester and just started showing but the buttons already felt like they were pulling at the chest, I don't think I'd be able to wear this for that reason as I got bigger, even though the belly would fit great

Loved this dress

Felt classy and cute while pregnant at work. Dressed it up with heels or down with designer tennis shoes, hugged the bump and my body beautifully. I wore it probably 6 times while I had it rented. My top rental this year by far!

Shows off your bump!

This everyday black knit dress is super stretchy, comfortable, and shows off the baby bump well. Recommend sizing up, as the shoulders/bust area is tight, even for someone with a straight figure. Dress runs long, fits like a midi on 5’8”

Figure hugging stretchy dress

Classic. Great with accessories and/or outerwear. With tights and boots mostly. A little more sexy, but can be covered up for more modesty.

gorgeous fit, could use more bust room

This dress is awesome. I loved the way it fit and it is def a 2nd AND 3rd trimester dress. The only issue is that I felt it was giving me a lot of cleavage. When I buttoned it up more, it stayed put but I kept thinking I would bust the button open, so I like wearing a cami under it just in case.

This is very comfortable but looks dressier. I wore it 8mo pregnant and there is lots of stretch.

Great if you prefer tight fitting maternity dress. Material and color make it flattering while showing off the bump.

Fit great at 35 weeks!

Stretchy, stylish, comfortable and flattering! Wore this all night and loved it. I sized up (small -> medium) to make sure the buttons didn’t pull over my chest and I’m glad I did. It has the ruching on the sides which was very helpful for my 35 week pregnant belly. Highly recommend!

Great dress, soft material, sexy fit. Only issue is I couldn’t wear it because the second button wouldn’t stay closed. Hope it works for someone else because it’s a fabulous look.

Super tiny!

I sized up and this was still VERY bodycon style which I wasn’t hoping for (hence the sizing up). Nice dress but would size up 2x if I rented again (at least while 31 weeks pregnant!).

Small in the bust but very cute

This was really cute and exceptionally comfy. I rented it to wear for work, but it was gaping in the bust (and was very body con), so wore it to dinner instead. I would wear to work in the next size.

Very cute, bust runs small

As with all soon items, I find this runs small. I rented a L, and still had trouble with the buttons in the bust pulling. Otherwise, it's very soft and comfy. I am 36 weeks, 171 lbs, 5'8 and am busty.

Nice but surprising not in a good way

I thought this was a V-neck dress from the picture, but it's actually a collared dress with buttons at the top. The bottom button near cleavage liked to pop open, even with the thinnest bra I have and I am not busty... at least, I wasn't before becoming pregnant. So, beware of that! Might need an extra safety pin to be safe.
