Bought it

I ordered the S and XS. I like a more fitted look, so I wore the XS and bought it. The slit is higher in the XS. Barely see thru. Very comfortable

Sexy and comfy loved it !

Felt amazing in the dress such a great color. Super comfortable and the draping hits in all the right places. Didn’t want to send back! It’s confusing when first putting it on but I used the model pic as a guide and figured it out.

Best party dress

This dress is hot and COMFORTABLE! Ideal for a night out. The top part is a little see through just keep that in mind that you might need a strapless bra.

If this dress doesn’t make you feel sexy nothing will

This dress is a showstopper. The bold red color is stunning in person and really pops, and the slits and subtle cutout add just the right amount of edge without being too revealing. This dress makes you walk with a little bit of extra sass!

JUST RENT IT!

I wore this dress for date night with my partner and I am going to say 10 out of 10 highly recommend. The dress was sexy and classy. The part I love the most was the neckline and my exposed clavicle. Well, the material is thin, it didn’t bother me one bit. I simply owned it and felt like the sexiest woman in the room.

Lady in red

This is double layered mesh so not necessarily see through but some may be uncomfortable without a bra or pasties. I didn’t wear either as I felt it drew more attention. The straps helped to keep things in place. But you can maneuver these straps to your comfort level.

Stunningly Elegant (Once You Crack the Strap Code!) 👗

I absolutely loved this dress! The bold red color was striking and the silhouette—so flattering. It felt both beautiful and elegant, making it a perfect choice for formal night. Plus, it was incredibly comfortable, even with the dramatic slit and fitted design. I received so many compliments! One caveat: getting the straps right was a bit of a puzzle. It took me about 20 minutes to figure out how to situate them properly—definitely not a throw-it-on-and-go dress. But once it was on, it was so worth it.

This new piece doesn't disappoint!

Would fit anyone as there is a good amount of stretch but also holds you in. Getting all the straps in the right spot is a little confusing so having the RTR link handy is probably helpful!

SEXY Red Dress

This dress was everything and more!! I felt sexy and powerful in it. The neckline is a bit strange but it’s stretchy and you can wear it multiple different ways (I crossed it in the back for a high neck look). Had to wear nude pasties under it because it is see through.

Loved how it fit. I will say it’s a little sheer in the chest. I ended up adding cakes for comfort.

Favorite Dress EVER

As soon as I tried this on, my confidence shot through the roof. It is not only the most flattering dress I've ever worn, but the fabric is so soft too. I wore this to a dance event, and the way it moves just adds to the appeal of this dress. Already looking into buying, I'm so in love.

No words. Just WOW. I was worried the slit would be too high and open, but it’s not. Feel free to wear your usual size or smaller- forgiving, stretchy, soft and will relax to your shape in all the best ways. Big Kobo win💯

Love the fabric

It does not run small! I ordered a medium thinking that it did, but it doesn’t. Very, very comfortable and equally difficult to get the back to lineup straight. Actually a bit of a challenge to figure out how to put the thing on, but once you do, it’s fine! Also, you need a nipple covers. Only place where they didn’t really double the fabric enough.

Stretchy red hot number

This was my backup and it was a tough call not to go with it. The color is fantastic and the dress is so stretchy and comfortable. I did find the twisty straps at the top to be a bit annoying to figure out!

Gaga for this

Wore this to the mayhem ball- quite comfortable, it was helpful to have nipple covers (though the outline of the covers could be seen through the dress if you were looking for it). The dress needed quite a bit of adjusting throughout the night because the straps kept shifting around. It’s quite stretchy, so it would likely be ok to be sized down for those between sizes. I don’t feel it was the most flattering on the midsection and because it was so sheer I couldn’t really wear true shapewear. Anyway it was a fun wear and a GREAT color and fabric, but the fit felt slightly off.

You’ll feel like a goddess

This dress is so hot! The sizing is perfect, obviously very tight through the top. I took a star away because it is very see through which I didn’t realize. Thank goodness I had a nude color bra and underwear or I wouldn’t have worn it. But material is comfortable, you’ll feel beautiful

Stunner with a few problems

This is a very stunning and unique dress. It’s definitely the show stopper you’re anticipating but it does have a few problems. First, it’s tricky to figure out the straps and they get a little stretched in the process of figuring it out. Second, it is fairly sheer. You could even see my pasties through the top. Last, for material this stretchy the sizing felt slightly off. This XS shouldn’t have been roomy but was in many places.

Lady in THE red dress!

Stunning dress! The fabric is super stretchy and flattering. Ronny Kobo usually runs small, so I sized up to a Small but honestly, the stretch makes it very forgiving, and I could’ve gone with my usual XS. Regular length is perfect on me (5’5”) and works even with flats. No shapewear needed—key areas are double-lined. One con: the red dye did transfer onto my white chair, so be careful around light-colored surfaces. Otherwise, I absolutely loved it!

I loved the color and style of this dress, however, I wish the top of the dress was lined. I had difficulty coordinating undergarments for this dress, so I only wore it for a photo. I would give this 5 stars if the material was thicker
