Light and perfect for a summer party. I could have gone a size down.

In love

This dress is so cute. The stretch in the back makes it feel tailored to you. It was a little low cut for me, but I wore a tank under it which still felt cute. I ordered the 10 and 12 and preferred the silhouette of the 10. Will rent again. Really loved it.

A must rent

If you’re between sizes, size up. I got two sizes and went with the bigger option but could have done either. Loved this dress. Adjustable straps and smocking made it fit like it was made for me.

Size 4 was PERFECT

Bow pattern is so playful & unique - there's also a little lace detail around the neckline. The spaghetti straps are adjustable & there's no boning so its very comfortable. The back has a smocking detail near the zipper so you can fit lots of bust sizes.

Simple, cute dress

What I really liked about this dress was the little lace detailing around the bust. It is a thin dress with some stretch so shapewear is advisable. I wore it to a casual backyard wedding.

Pretty, Slightly Girly, Great Fit

I have an hourglass shape, and it fit great. There was enough curvature in the shape of the dress without it being too tight or fitted. The subtle lace detail along the bust added a little detail to an otherwise "simple" dress. The bows were the perfect touch of girly. I'm 5'6, wore a 10 and it hit me long, right above the ankles. I still felt great in it!

Fun wedding dress

Great dress for a hot, outdoor wedding. I didn’t need to wear a bra as the top is double layered. My first experience with rent the runway went great!

Nothing great.

Wore this to work with a blazer and out to dinner with a leather moto jacket, it was fine, comfy, but nothing extraordinary

Figuring Out Reformation Sizing is Hard!

I’m a true size 4 and I sized up to a 6 based on the reviews. Overall, it was a good call to size up bc Reformation runs small. For me it ran small in the hips, but the chest fit perfectly. I imagine this looks best on individuals with small hips and no butt, which is not me, so it wasn’t as flattering as I hoped. The print is adorable and it’s very lightweight, best for summer or spring. I’m not totally sold that this brand is for me, but the designs are so lovely I’m sure I’ll try again.
