from 3284 reviewsI wore this dress to a bachelorette party and honestly loved it! The lace detail is so unique and pretty. I was a little worried at first that it might snag easily, but the lace is actually quite tightly made. I danced all night and when I got home, I didn’t notice a single snag. It held up so well and looked just as good as when I put it on. Such a perfect dress for a night out!
This dress is lovely! I wore it to my graduation party, and it was a hit. The fabric is comfortable, and the way the light catches the beads is just magical. It’s sophisticated and made me feel really special without being overly flashy. A great choice for a memorable event.
I was a little nervous about ordering online, but this dress totally exceeded my expectations! The bodice is incredibly flattering, and the beads catch the light beautifully. I got compliments all day long. Highly recommend if you want to stand out!
I have to say, this is one of the best dresses I've bought in ages. The A‑line shape is super flattering, and the strapless neckline is just right — clean, balanced, and not too low. The ruched detailing on the bust is uniquely designed! This dress is a total win in my book!
I honestly wasn't sure what to expect when I ordered this dress for my daughter’s junior homecoming, but I was pleasantly surprised! The color is exactly like the picture, which is rare these days.The tulle adds just the right amount of fluff without looking like a cupcake.She danced all night in it and said it was comfortable the whole time, not scratchy or tight!
This dress is perfect for those moments when you need something a little special but not a full-on gown. I wore it to a birthday gathering, and it was just right. It’s comfortable and the silhouette is really flattering. I’ve already thought about wearing it again for another event. Good value, I'd say.
Beautiful and well fitting dress!! I definitely recommend this to everyone! I ordered this for vacation and I was really pleased❤️.
Absolutely love this dress! I’m a curvy girl and wasn’t sure about the size, so I contacted Anna for help. She sent me a measuring guide, and I decided to go with custom sizing. So glad I did! The fit is amazing, the floral lace detail is so unique, and it gives great coverage without showing any side boob. The fabric is stretchy and comfortable too. Such a happy purchase!
I wear this dress for my 30th birthday. It was absolutely gorgeous. I will say that if you’re in between sizes definitely size up I’m normally US4,but I got US6 and just got the alterations. Material was a 10 out of 10.
I am absolutely thrilled with this purchase! The first thing I noticed was the high-quality fabric—it has a great weight to it and feels very premium, not thin or cheap at all. Most importantly, the sizing is perfectly consistent with the size chart, so I recommend ordering your usual size.
I absolutely love this dress! I received so many compliments from guests who kept telling me how beautiful it was and how well it suited my pale skin. It felt elegant and flattering, and I was really happy wearing it. Definitely one of my favourite dresses! ♥️
Quality was absolutely exceptional and made the most beautiful birthday dress! I paired it with the matching scarf and I can’t wait to buy more dresses from this brand. 10/10
This dress is absolutely beautiful and i can not wait to wear the dress for my party,the sizing is smaller so always size up when purchasing. but the quality of this dress is amazing and im so thankful to be able to find this dress.
The dress is perfect—it looks exactly like the photo, fits well.It’s not too short, and the quality is really top!

This dress exceeded my expectations! So comfortable and flattering, had to share a photo of how it looks on!
I ordered this for my bfs prom and it was stunning. Kristy constantly emailed me to make sure all the custom measurements were right. I ordered the color as picture but it looked a bit brighter and more unique and it just made me love it even more. It’s great fabric and super thick yet easy to dance with. I loved the scarf, but after a while it broke because a lot of people were stepping on it. I even ended up emailing her to get the fabric for my boyfriend’s tie and she was so nice about it. I have come back this year looking for another dress because I was so pleased with Roman Bridal. Please buy from them because you won’t regret it!
Beautiful, the dress that should never be missing
The material a good cotton, the measurements fit perfectly. I like it very much
