Comfortable, flattering, beautiful

Great for fall weather I loved this dress for a day walking and shopping around Madrid! I dressed it down with sneakers since I was walking so much. Fit was so comfortable and light.

Classic and comfortable

I loved this dress. It was perfect for winter with the sleeves. It was comfortable and easy to wear. As other said the skirt could be see through with the right light but I believe the material is to thick for the most part to be see through. The midnight blue color was beautiful. Would definitely rent it again!

Beautiful work dress

I loved wearing this to work, but it could be nice for an elevated dinner or event. I couldn’t really tell if the pleated skirt part was sheer..so I’m not sure if I showed my butt all day (I’m tall), but whatever!

Stretchy, good thickness

The picture doesn’t do it justice, as it was a very comfortable dress and I received a lot of compliments. Just was a little plain at the top for me

It was a bit large!

It was a bit large in the shoulder area and hips but it was super comfortable and I would rent this again. I ended up wearing it with a sweater on top of the dress because the bottom of the dress is so flattering.

Extremely comfortable and polished

I’ve worn this dress both to the office and to a conference. It is extremely comfortable and tailored enough for a professional environment. The material is very light weight which contributes to the comfort.

Nice Fit

I usually don't do form fitting, but the fabric is thick and heavy so had a nice weight to it. I wore it to a formal wedding with pumps. Got several compliments. Definitely recommend

It fit nice, with shape wear it would have been fine. I didn't end up wearing it because it seemed too formal for my holiday party.

Weird sleeves

I wore this dress to film a YouTube video and it looks nice on camera but didn’t wear it out because the sleeves were cut weird. The shoulders puffed up. It’s a shame because otherwise it fits nicely.

Gorgeous, but not tall-friendly!

This dress is gorgeous! The idea is simple but well executed. The mid section of the dress is opaque, but the arms and bottom of the skirt are see-through. It was a very flattering fit. The only issue is that I am 6 feet tall, so the see-through part of the dress starts way too high (like shockingly high). I wish they created a tall size so I could wear it out of the house : )

Beautiful color and high-quality, just a weird in between a formal and casual

I ordered this for a function, but it read too casual for that event. I even brought it with me on a trip to Europe to wear out for dinner, but it's just this weird middle ground of two elevated for daytime wear and two casual for much else. Also, the material can be a little see-through, so be mindful of that.

Dust wear but could be really cute.

I'm very tall and this was so cute but it's very sheer until the crotch area on me and it wasn't appropriate to wear at the event. I wanted to wear it too.. that said, I think it would be really cute in the right occasion with somebody who is a little no shorter torso and maybe a little shorter

Unflattering and strange fit

Weird fit in the shoulders and the opaque part of the skirt is extremely short - should have listened to other reviews, this is not made for taller people.

The most bleh dress if there ever was one

This isn’t even a “I guess I’ll use it to free that one spot I can’t find anything to fill” dress. Talk about the most boring and ill-fitting dress. I thought it was boring but that I’d wear it to church or something, where I’m not trying to make any fashion statements. But no thank you. What a total drag of a dress. Also, it runs large and yet still clings only to your tummy.

Didn’t not wear

The bottom material is somewhat sheer so with it not covering my rear end I was not comfortable wearing this
