Love, love, love

One of my fave rentals ever… looking into purchasing!! So comfortable (silky, slightly stretchy) & beautiful, if you can’t tell already, I loved this dress. Could have worn it all night. Tho I generally wear a size 8 (sometimes squeezing into a size 8), I went up in size to a large for this dress. As I can’t say how the medium would have fit, I did not have to wear shapewear nor worry about eating too much. I did not wear a bra but wasn’t worried about it being too loose up top. Everything about this dress worked perfectly for me!

Elegant and Sexy!

I loved everything about this dress. It fit perfectly. It highlighted all the best parts and hid all my insecurities. I didn't have to use boob tape or even wear a bra. It was sexy without being vulgar. I wish I could keep this dress!

Super comfy!

Really loved this dress - it was super comfortable in warmer weather (80-90 degrees). It does run a little large but was able to keep it secure (and have piece of mind!) with double sided tape.

Great dress

Wore this dress to an outdoor black tie wedding in June (high 90s). It was a last minute rental and worked like a charm. My only notes is there is a liner that only came down to the bottom of my butt and then would also ride up half way Not quite sure what its purpose was. I had bought sticky boob things to lift my girls bc I did not want to wear a bra/did not have the right one. The dress clings beautifully but I did not want any lines. And since it was 1 million degrees, they kept sliding out I took them out before the wedding even started. Def review what under garments before you start to leave. Would wear again

Gorgeous, classy & comfortable

Great dress! Didn’t have to wear shapewear, as the front hides the belly area. Length was perfect with 2-inch heels. The plunging neckline is too low for a bra, so I used boob tape, and it worked well. Great dress, would definitely wear again!

Nice fit, fitting but allowed to have to have perfect posture at all times!

I was worried that the long might be too long but in fact it was perfect length, I recommend if your 5’9” to definitely get long to be able to wear a heel.

Flattering + comfortable + beautiful

Wore for a gala. I was 4 months postpartum, 5'3" and roughly 135 lbs. Super flattering with my postpartum mom belly. Order both small and medium. Either would have worked but went with the small. Would rent again, 100%.

This dress is the bomb diggity!

Everything about this dress increased my confidence: neckline, ruching, slit, length. It was so forgiving and flattering. I did have to tape the girls to ensure no one went exploring but I didn't have to wear Spanx, so amen to that. The only thing that was challenging is that there is a built in slip that is supposed to go down below your thighs but because I'm an hourglass figure, it didn't make it past my waist. Because of the ruching it wasn't noticeable, but it would be great if that was removed.

The fit is true to size. I like the deep v and the slit. These details really make this dress standing out. I am 5'5", 126 lbs and wearing size small. The dress is a bit long and I have to wear 4 inch heels.

So comfortable and flattering!

This dress fit so well! Highly recommend as it was super comfortable and sexy too with the plunge neckline! I wore this for a formal wedding and loved the classy look. It was important that I wore something I could dance in and this was perfect for that as well. I wore a strapless bra and had no issues with it showing. Buy this one!

I liked this dress and looking back it was great

Fit was good maybe a little bug for me. I am 5'7" 160lbs size 34D athletic build and I had room in the dress. I didn't like how at the waist there was one side that was tight and the other side that was loose I thought it looked weird on me

LOVE!! Soft and Stretchy :)

Cinq a Sept never disappoints me. I rented this for a Gala. The only thing to be aware of is that it is kind of long. I’m 5'4 and was wearing heels and sometimes it would catch.. I tend to stay away from deep Vs because my boobs are small and weird. But tbh, I loved this. I did not wear a bra...I would maybee invest in some nipple tape or whatever it's called. But I did not wear it as I didn't think it was terribly obvious. I’m 5'4"; 115-120lb; 32B. I usually wear a 0-2 and an XR fit perfect.

Beautiful

The dress was comfy, flattering (no spanx needed!) and elegant. I wore with 3.25" heels and it was the perfect length. Didn't even need a bra which is a rarity for me! Would 100% rent again for any black tie affair.

Comfy black tie wedding dress!

Wore this as a bridesmaid in a black tie optional wedding and I got lots of compliments! It's a Jersey fabric that hugs the body but not unflatteringly so. The draping makes it look fancier--I am a 6-8 in dresses and the medium fit perfectly!

Postpartum dream dress

I rented this for a black tie wedding (almost 4 months postpartum). It fit great, was very forgiving in the midsection if you haven't lost your tummy quite yet. I wore a deep plunge bra that worked great! I'm short (5'3") so 4 inch heels had my dress barely skimming the ground so make sure to wear some tall shoes if you're short!

I'm not one to leave reviews (esp with photos) but this dress was a last min add for me, and damn, I wish I would have kept it. You deserve to feel this amazing in a dress! It's the perfect material, cut, etc. etc. I received so many compliments both IRL and on photos. I wore this for a cocktail rehearsal dinner but was prob a little overdressed. Would recco for a cocktail-formal reception!

This was for a black tie wedding in August in Santa Barbara.

This was a black tie wedding and I did not want to wear black but the other dresses did not work out. This ended up being perfect. Very flattering, especially at the waist. I am 5'5" and wore 4" heels and the length was perfect. Loved the plunging neckline and the slit. Great dress!

I wore this to my commencement ball for my college graduation, and it was fantastic.

I was really worried about length going in, but I didn't even feel like I had to wear heels with it. I actually ordered this as a backup, but it ended up being my favorite. The dress was in great condition, and the fit was super comfortable. I didn't have to worry about wearing a bra or anything. It's understanded and not too much, but the dress looked fantastic, and I would totally recommend.

Simple black dress but a shop stopper

Wore as a back up for a black tie wedding when my original option didn't work. Wanted a simple black dress as a safe option. The material is forgiving and neck line/slit were sexy. I got a ton of compliments. I'm 5 ft 6 in, 125 lbs and 32 DDD amd wore a small. The top was a little saggy-xs may have been a better choice. The neckline is plunging. If you are busty you'll need an undergarment plan. I used boob tape which worked fine. Overall very pleased with this dress.

Backup dress becomes shoe stopper

I was actually sent this dress when my original order didn't arrive. And it was a hit! Very forgiving but flattering shape... I probably more of a 6/medium but the small fit great due to the jersey-type material. Neck line is PLUNGING... like to bra plunging but the material and shape makes it fine to not wear a bra. Comfy, classic, sexy without going over the top.
