A perfect formal wedding dress!

Loved the color especially for spring/summer and fit well especially for my being so petite. Wore it with heels and it worked really well for an outdoor wedding!

True to size

I’m a size M / 8, 5’9” approx 170 lbs. Some reviews said size down, and I did order the small as a backup, but the medium fit like a dream. The back has a little stretch panel, and the straps are adjustable. I felt amazing and got so many compliments. The length was perfect for a formal wedding! The color reads like a silvery purple depending on the light. I have to say - excited to order RTR for my next event!

One of the best dresses I’ve ever worn

Loved this dress SO much 10/10. It was so comfortable all night, is lined, and was tight enough up top to allow me to dance with no worries about slippage. The fabric is silky and looks stunning in light. Also love the tiers! This dress seemed a little longer than I expected (I thought it would be a bit shorter not a full length) but I am also short. Would recommend for any wedding guests!

Fun wedding guest dress, ran a bit big

Got lots of compliments but the waist and chest were a bit big. It was doable but just be wary.

Great Tuscany Wedding Guest Dress

It was so comfortable, stretchy, I was worried about the tiered skirt being too poofy but it was super cute and I would totally recommend. No bra needed too which is always a plus

Perfection!

This dress was BEAUTIFUL!! I'm 3 months postpartum and it made me feel great. It's flowy, comfortable, and moves beautifully. The adjustable straps were helpful, and because it was stretchy, I was able to put my wireless pumps in with ease. Highly recommend!

This dress exceeded my expectations. It was so comfortable, no bra needed and it was stunning on. The ruffles weren't too much, It kept its shape and looked great. So many compliments.

Lovely Garden Wedding Dress

This dress was so flattering, comfy, and received a ton of compliments. It’s a little on the heavier side since it’s well lined so keep that in mind for summer 😇

Rent it!

I rented this dress for a wedding where the dress code was colorful cocktail, and it was perfect! I found it fits true to size, and was very comfortable. I’m a 34A and was able to go with just petals, the adjustable straps are a huge plus. Great color and fun movement on the dance floor, I received a ton of compliments! This is one I was sad to send back!

I really loved this dress— perfect for the occasion and fit nicely!

A little tight in the bust region but it has adjustable strap so that was helpful. The zipper is pretty dainty and so you have to be extra careful when zipping yourself in— I would use some extra hands if possible!

Gorgeous dress! Got so many compliments all night.

Dress was lightweight and so fun to move around in on the dance floor all night. Straps are adjustable which is great. Has a slight sheen to it. Very lightweight and breathable. Wore for an outdoor summer garden party wedding

My favorite RTR ever!

WOW! I am no stranger to RTR and this was by far my favorite dress I’ve rented! It is sooooo comfortable. Honestly it felt like I was wearing a nightgown all night. The tiny little plunge in the neckline is a super fun touch, but wasn’t too revealing. I am a mom who has breastfed 3 kids and I did not need to wear a bra… and I nevvvver go without a bra. Could not recommend this more!

I ended up ordering an XS rather than my usual size small due to the reviews- and I was glad I did. Definitely size down one size. The dress was such a statement and was so comfy. Compliments all through the night. Honestly will probably end up buying

Really pretty! Wore to a wedding and got a lot of compliments!

If you are small chested the top can be too big! I would recommend sizing down for your second size you order.
