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.

Sexy and fitted

Wore for my birthday dinner. Lots of compliments and my husband loved it. It is sheer, but the layers cover everything. I loved wearing 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, easy and perfect

Perfect red, it’s like a mesh almost mummy dress? Feels like you’re wrapped in it. So fab. So many compliments! I wore it several times. I wish I could buy it.

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.

Pretty color and nice material. Shows everything so I needed shape wear. Slit is pretty high too. Very sexy and fun dress!

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!

Stop Traffic in this Dress

I wish I could have ordered this dress in a small petite because it was long, and I had to carry it when walking up stairs. However, I felt sexy in the dress for a night out on the town.

HOT!!

Very sexy but definitely needs breast cups and you can’t wear a strapless bra.
