Got many compliments on this one!

Probably one of my most favorite wedding guest dresses. Loved the color. So light and flowy and quite comfortable! The back of the dress is stretchy so I sized down to a S instead of a M. Great length too.

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!

Beautiful wedding guest dress

Loved this dress! The dress earned many compliments, was super easy to style, and was comfortable for sitting and dancing. The color was lovely and neutral. I went with the small over extra small for easier zipping up, but both fit.

Fun wedding dress

Ended up wearing a different dress but thought this one was cute and comfy! I wish I had gotten one size smaller since the back is stretch and I think it would’ve been more flattering.

I loved this dress. I got SO many compliments on it at a wedding. The straps were a little annoying and couldn't adjust but the overall dress made up for it.
