Stunning wedding guest dress

Beautiful baby blue color, super comfortable, great shape for those with small waists and wide hips that want to cover their arms. You can button the boobs area or keep it open. Lightweight. Wore to a wedding in Chicago in July

Perfect for a Boy’s - Baby Shower

Rent this stunning dress! Great fit. Endless compliments. Love that you can tie in the back and further accentuate your waistline. Flowing and stunning. Slit help to keep my legs cool on a warmer summer day. Overall so complimenting and it’s one of my favorite rentals recently.

Spring garden wedding perfection

The invitation said to dress for a "spring garden wedding," and I could not have picked a better dress. It was so soft yet striking, and even though it was demure, it was quite alluring. You may notice that I tied the sash differently than some of the other wearers; when I tied it in the back, it looked very matronly on me. I had to bring it back to tie it in the front to give it a sexier, more flattering shape. The dress was super comfortable, too. Note that it has a high slit.

Fit perfectly and very comfortable.

I did have to wear a higher heel with it because it was long but I loved this dress so much. The only thing is that the clasp may have needed a fix but it wasn't noticeable

Cute, warm dress

I wore this to an outdoor wedding in England’s Lake District where the temperature the day of the event was 62 F and rainy. I wasn’t cold at all and got a bunch of compliments. I was worried it was a bit little house on the prairie, but the neckline and slit made it fun. Also, it read very blue on me and not beige or white!

Perfect cocktail spring/ summer wedding guest dress

Didn’t have to wear a bra, need I say more? XL fit me perfectly and I have a larger bust + wide shoulders. It sat perfectly and came with not wrinkles. I didn’t use the button in the front, but could be less revealing if you used the button 10/10!

Perfect for a Spring Wedding

I got so many compliments! Kept me warm for an outdoor reception but the light color was nice for the spring time feel. The small fit well, longer than the original picture (which I expected) but wasn’t stepping on the bottom of the dress with my heels at all. Would definitely recommend!

Favorite Rental! Super feminine, flirty, but classy!

I loved this dress! My favorite rental to date! I did use a safety pin to wrap the ties around my waist because I am not a fan of doing a bow and did use fashion tape for the bust because the hook and eye did gape the dress so I did with out and just taped and it was perfect. Love loved the fit and the style!!! Got plenty of compliments!!!

Cute flowy dress

Ordered this dress for an April wedding. I ended up not wearing this dress as I chose another one from my shipment. I got my usual size S and it was the right fit! Length would be perfect with heels. I was 13 weeks pregnant when trying on and it was a nice flowy fit to hide my bloat!

So flattering - no special undies required!

I loved that I could slip this dress on over my head (it’s stretchy and elastic - no zipper!) and go. No special bra or underwear or fashion tape was required. It even has a hook and eyelet if you want to make the top less revealing. Perfect length - even for us short girlies (I’m 5’4) and the perfect level of formal for a spring “black tie optional” gala.

RTR TEAM REVIEW

This dress is SO flattering and comfortable!! The perfect dress for a Spring or Summer wedding. It has an attached bow that ties in the back and a slit up the left side of the dress which are both really nice details. It's a super lightweight and breathable fabric too. The only downside is there is not side zipper, and it was slightly snug getting over my head/shoulder, but once I got it on it was incredibly comfortable to move around in.
