Gorgeous Floral Dress for Day to Night

Obsessed with the beautiful fit, fabric, and print of this gorgeous floral dress; easy to dress up or down and looked as gorgeous standing up as sitting down! TTS although tight waist fit as mentioned in other reviews and petite friendly. So wish I could buy, a MUST rent!

Bust in Show

Overall the fit was good, I probably could've gone up a size for more comfort in the bust but it delivered! If tied too tight, straps will dig into shoulders.

Beauty is pain

Wore for an evening outdoor even. Loved how I looked, hated how the straps felt in my skin. After a million times of trying to tie the straps per the picture, I gave up and crisscrossed them. Overall, would wear again but your skin will be crying.

Size up!

This dress is super cute but size up if you have any boobs or hips. The slit is supposed to be on the side but with my wider hips, it was dangerously approaching between my legs.

Cute!! Many compliments

The boob area is small and I’m a 34B chest is 34, waist 27, hips 37 I got a size 2/4 but I wish I would’ve picked 4/6 because I think this is made for girls with a short torso, my torso is long and caused the slit to be close to my crotch - which made dancing difficult because

Reliably great.

This dress is so flattering on most - I’ve worn in other colors before. A fabulous option for petites. Beware, it’s busty! You’re very likely to feel amazing and confident in this dress. Be sure to size up - Reformation runs small.

Lots of compliments on this one! The chest was a little big so I added padding inserts to help out. Other than that it fit well!

Love, love, love!

I felt so pretty in this dress, as someone who normally doesn't love drawing attention to my belly I felt that this dress was really flattering. I wore a shawl over it because it was definitely a thin material, but I would almost certainly rent this piece again.

OBSESSED

Highly debating buying this dress because it is everything. I got so many compliments on this and it was so comfortable to wear. Straps are adjustable if you can manage to untie the bows. Cannot recommend this dress enough.

Absolutely loved

This dress was perfect for a summer wedding! Perfect fit, I nice light fabric. Needed someone else to tie the straps tight enough, but they stayed all night. I’m usually between 6/8 and the 8 fit perfectly. Would 100% recommend!

Wore this for a summer dinner party in the French countryside. It was during a heatwave and the dinner party was outdoors! This dress was flowy, breathable and comfortable. One of my all-time favorite rentals!

Loved everything about this soft and thin dress. The perfect little slit and I didn’t need a bra for the cups. It’s also adjustable if you need it to be a shorter bust line.

Bombshell dress

I ended up wearing my backup size, which was one size up, but it was fitted in all the right places. The slit is a little high, so beware of that if you aren't comfortable with a slit, but the length was perfect. You also will need help with the straps because they need to be tied individually. LOVED it though. And received so many compliments.

Perfect for a summer wedding

Wore this dress to a wedding in the height of a 100+ degree heat wave, and it was great. The material was not too heavy, and the slit was just the right amount of spice for a family wedding. Loved it!

Perfect for a summer destination wedding!

This dress was way more flattering than I expected! It has rouching (I think that’s the word) in all the right spots to help feel confident. The leg slip was fun too but be wary it goes up super high! I ordered a 4 and a 6 and the 6 just fit. Would recommend trying your true size + sizing up instead of down as your backup!

Love!!!!!

Dress was beautiful and an even more pretty color in person. I am typically a size 4/6 and the 6 fit great. The overlap slit and ruching was very flattering and adjusted well to my bigger hips. The bodice was a little long on me (likely made for taller gals) but because of the ruching I was able to pull it up a little bit for it to not sit too low on my waist. Bra cups fit me perfect but may be more of an issue for larger busts.

Sleek and cute dress that fits nicely

Wore this dress to a cocktail attire wedding, and it was perfect for the outdoor SoCal weather. The fit was super flattering with the cinched waist, flowy skirt and bodice that was form fitting -- but not too tight or uncomfortable. The slit looks nice, but for me was a bit higher than I realized when walking and sitting. I wore spandex shorts under. The straps, while thin, held up the whole night, but it may not be sufficient for those with a very large chest. Used steam to get the wrinkles out. Would recommend!

Easy to dress up or down

Beautiful dress that can be worn for all weather! Looked equally good plain with sandals as it did with a leather jacket and boots, which is what I ended up wearing since the weather turned on the day of the event. Easy to dance in, flattering, and showed just the right amount of leg and cleavage.
