I ended up wearing the bigger of the two sizes that I order and it fit pretty snug so I would say it probably runs a little small. But over all I loved the dress! I got so many compliments when I wore it and felt really comfortable in it as well! I highly recommend!

YO SIZE UP IF YOU CAN!!!! I was not breathing the whole night but it was worth it because this dress was so flattering. Got so many compliments on it too. Would wear again if it was a size up lol.

I followed the advice from other reviews and ordered larger than usual. I typically wear a 6 but the 10 fit well. By the end of the night it had stretched out a little, but it was comfortable the whole time. Being able to slip the straps onto my shoulders helped for setting up the venue. I'm a 34A and pulled the dress up a few times, but it didn't feel like it was constantly slipping down

Overall great! My husband was a big fan. The fabric has no give so it was a little tough to get comfortable all night.

I usually wear a 4-6 and I'm glad I sized way up per the other reviews, I wore a size 10! It's flattering and the bust stays up just fine so you don't have to constantly adjust yourself.

Loved this dress. Followed the review advice and ordered way up, usually a 6 in this brand, ordered a size 10 and the fit was perfect. Hid my baby tummy and made me feel great.

I had trouble with the zipper, but the overall fit was great.

I absolutely loved this dress. It was a little snug up top, but the style was perfect for the wedding I attended. It was comfortable all night and the material wasn't itchy. I would rent this dress again if I got one size larger.

Snug fit, I wear size 4-6, and always choose 6 for my Reformation size. Arm holes are tighter as others have mentioned, but I loved the dress so much I didn't mind too much.

I got this for family pics. Luckily I was planning on wearing a jacket because I couldn't zip it up! I sized up to an 8 but probably should have done 10 or 12...I'm usually a 4! Still wore it and loved how it looked just couldn't zip it up.

Runs small

I rented this dress for an engagement photo session, and it was absolutely beautiful. Definitely agree with all the other reviews that you should size up! I'm usually a size 4/6 but the 8 fit me perfectly. The fit/fabric aren't very forgiving so I wore Skims underneath to keep it looking smooth. Only slight con was it wrinkled rather easily after sitting in it. Other than that I think it's a perfect dress!

Absolutely beautiful. So flattering. I felt beautiful and got many compliments. It runs slightly small so I went one size up. The perfect dress!

Reformation is one of my fav designers on RTR. I wasn't disappointed in this one. The fit is so flattering and hugged my small frame. I will say though after a 3 course meal it was a bit snug but to be expected!

I had my mind set on another dress, rented this dress as a backup style, and fell in love with it! Reviews suggested sizing up as it fits a little tight in the chest and the next size up worked perfectly for me. Not too hot even for an outdoor summer wedding. Loved the way it looked and was very comfortable for a long day.

Love this dress! I normally wear a 4 but the dress runs quite small so i wore a 6 and it fit great!

This dress was perfect for a backyard wedding in AZ in feb (70s). I agree with the other reviews to size up since the ribcage is very tight. I am normally a 6/8 and was glad I got the 10R. Will rent again!

The fit was very tight around the bust area (I am a 32C, 105 lbs, 5'1 inches) so my boobs naturally were pushed up but it looked super good. I also didn't like the dress as much off the shoulder so I pushed the straps on my shoulder and I really liked that look. Perfect for a wedding!

Rehearsal dinner. Pretty tight on the abdomen and breasts. Order up at least 2 sizes

I loved this dress- the neckline was SO flattering, it hugged the waist, had a romantic look. I'm usually an XS and the size 8 was tough to get into. Definitely needed help zipping up! However, i still loved the overly look. Keep in mind that its very snug in the bust

I was able to make the a size up work but it was still so tight. Still wore it but was a bit uncomfortable all night.

Very romantic dress. Fit is tight!! It was difficult to breath and required an extra set of hands to zip up the back. Highly recommend sizing up ...

Definitely size up or you will feel like you're a sausage bursting out of its casing. Beautiful dress and beautiful colors, really wish I could have worn

I wear a 4, rented a 6, and still needed to go up one size. It's very tight in the waist, but fit everywhere else. I couldn't even have a bra on with the dress. Wish I had the right size, because this dress is so cute and stylish.

So, yes this dress runs very small. I am a usually a size 4 in dresses and I did have to go with a size 8. The size 6 might have fit if my shoulders weren't so broad but the 8 was fine. However, I did wear it with the sleeves which I thought was cuter and if I wore it with the sleeves down I would have had to keep pulling it up. Anyway, I got loads of compliments and I felt really good in the dress!

Very pretty dress but I definitely recommend sizing up! I ended up wearing this dress and it was subtle and feminine. I love that you can switch from on or off the shoulder.

Beautiful. Not great for a hot day as kinda thick & synthetic fabric. Love the colour and style.

Beautiful dress but wayyyy too tight on the bust. I already went up a size and it was still tight...

This dress was amazing and looked great! I am a size 4 (5'10" 135lbs) but I did end up wearing the size 6 and it was still a bit tight. However, it was super flattering and perfect for a September wedding. The sleeves are stretchy but the rest of the dress is not stretchy at all. Size up for sure.

I was nervous to rent this dress because of all the sizing issues left in reviews by previous renters. The 10R ended up fitting perfectly and the dress looked beautiful. The only complaint I have is how busty I felt the dress became as the night went on.

The dress is beautiful but sadly I couldn't wear it since it felt too tight around the ribcage. I was supposed to wear it for my engagement photos but ended up getting rescued with replacements.

I'm so disappointed. I sized up because of all the the reviews and this dress won't even zip up. I'm typically a size 6 in dresses and would probably have to go up to a 10/12. I definitely wasted money on this one despite the fact that it's beautiful otherwise.

I really loved this dress!! I am sort of in between a 2 and 4 and the 4 fit well. I've found with reformation dresses if it has the smocked stretchy backing I wear a 2 and if it doesn't I wear a 4. This one doesn't and it really has no give at all. It fit tightly but it did not make me uncomfortable. The arms were super beautiful but did get a little itchy after a whole night of wearing. I dressed it down and wore with curled hair, white sneakers, and a jean jacket. Would definitely wear again!

It's not ideal for big boobs, but it's so adorable I wanted to wear it anyway.

The dress fit beautifully everywhere except for my boobs. It was actually so tight I didn’t zip it all the Way up to give my chest more room. I was able to get away with it because it was pictures but if it were for an event I would have needed a 6

This dress was so fun to wear. It fit the boho theme perfectly at this wedding. The color and cut were perfect. The material is light so it wasn't too hot on the dance floor! The only complaint I have is that it was a little right around my hips and waist. I have a pretty small waist so the 4 being small is unusual. Otherwise it was the perfect dress! I'll definitely rent from this designer again.

I ordered this dress for my engagement photos and it did not disappoint. My fiancé even offered to buy it for me he liked it so much. Does run small, had to wear my larger back up size and even that required some muscle to zip

I've owned Reformation before, so I knew what to expect. The material has no stretch and is not very forgiving. If you're in between sizes definitely size up! I wasn't able to wear a bra just because the bust was so small. I made it work though! The style is simple, but feminine. Overall a really beautiful dress!

Amazing dress! I usually wear a 4 but had to rent a 2 since it was the closest size available before the event, and it still fit. The 2 was a bit snug but it worked out since its strapless and I never had to adjust the top. Highly recommend!
