Cleavage — but stunning

I definitely didn’t need to size up (I’m a true 8) but did after reading reviews. It fit well but the top could have been a bit tighter since it was so plunging. I wore a strapless bra for a little more support but def didn’t NEED to.

Girls brunch

This dress is adorable on! I wore it to a girls brunch and received so many compliments. I sized up a size based on the reviews and I’m glad I did since there is no stretch. I’m normally a size 4, but rented a 6. Also would be great for taller ladies as I’m 5’3 and it hits below the knee.

Lots of compliments! Perfect for a summer wedding. It is a bit snug in the waist so definitely size up.

Flattering dress

This runs a tad small. Ordered my normal size and it felt like a squeeze. The material is stretchy and really hugs your curves so I made it work. Note that the thin stretchy material also means that it is less forgiving if you plan on indulging in a big meal. My favorite part of the dress is the sleeves and neckline - really pretty from the back as well.

LOVED, almost bought it!!

Loved this dress! I wore it for bridal dress shopping & brunch with my bridesmaids and it was perfect. I should’ve maybe sized up 1 size though because my back is a bit wide and athletic that it was hard to zip up by myself. I’ll probably rent a size up next time and if that fits perfect I’ll be buying it.

dream dress

this is one of the most flattering dresses i have ever worn. It is quite snug around the torso, but the back is stretchy so it never feels uncomfortable. i wore it all night at a formal event and received many compliments. the sweetheart neckline and dainty sleeves are so dainty and create the slightest hint of sexy cleavage (might be tough for larger breasts), the pattern is beautiful, and the length is perfect. i love the way it slightly flares out at the bottom. I may buy this dress, it is a dream.

The perfect dress

I am usually between and 8 and 10– I went with the 10 based on other reviews and it fit but the next time I rent this (and there will definitely be a next time!) I will go with the 8 due to the give in the back. I’m smaller chested, so there was some gaping for me with the larger size. I loved everything about this dress and am seriously considering purchasing it. I did look it up online to see if there were different prints and found one that I really like— I like the blue and white (almost toile) but I think I would get more use out of a different print because I live in an area with a blink and you’ll miss it spring season.

Comfortable, flattering, and appropriate

I loved this dress so much I almost bought it. It fits in all the right places, the neckline is incredibly flattering, the length sits right below the knee, and the pattern is so beautiful. For broader ribcage ladies (36 band +) it is slightly tight, but in a way that it helps your shape. I was worried about the color making me look washed out but it was totally fine—would look great on any skin tone.

Size up, Elegant, & Perfect Length

Worn for graduation & was the perfect length for sitting down (ruffles hit just below my knees) & with my graduation gown (not too long). It is fairly small - the button on the top of the back fits fine in a size 2, but I couldn’t zip it up all the way even though I’m normally a size 2. The next size available was a 6 and that is what I was wearing in the pictures - it still was fairly snug below the breast but sleeves and length were perfect! The ruffles, bottom half, and sleeves were still flowy.

Runs small, but great fit once you size up!

I’m normally a 6-8 depending on the dress. I needed a size 10, which wasn’t available. The size 12 was big, but worked fine with a little fashion tape! I would recommend this dress.

I thought this dress was very pretty and comfortable. The hem of the skirt went below my knees, which was unexpected but not a deal breaker.

baby shower perfection

Sized up (Usually a 6, got an 8) which I think was a good choice, made it more comfortable. Was able to wear a strapless bra and length was great.

Taking the advise of other reviewers, I sized up to a size 6. The fit is very flattering! The zipper is a bit stubborn, but with the help of a friend, all was well.

Love this dress and tons of compliments!

Wore this for my daughters baby shower and everyone loved it. Great fit and very comfortable. I’m 58 years old, 5’6” about 150 lbs and wore the size 8. I think a 10 might have been better in the chest area but only the 8 was available so based on reviews I took the chance and it was fine. I would buy this dress if I could because it’s youthful yet classy. Highly recommend!!

Comfortable, elegant and demure

This was nice to wear on a date. It's great for petite women given the cut. I didn't wear a bra with this and I felt fine and there were no nipple issues. This tends to wrinkle easily so be careful sitting down

Wore to a baptism, the chest may have been a bit low for church but the cap sleeves and tea length felt very appropriate yet not too conservative. Beautiful print, very comfortable fit throughout.

Elegant but perfect for summer

I’m petite and this hit me at a perfect length. If you have a larger chest I’d size up, but the back of the chest was elastic so there’s more give.
