Gorgeous mini dress!!!

Loved this dress, it's definitely not very forgiving and tight. Thick material but soo gorg!! I have larger chest and the L fit everywhere except was a little big in my chest. Needed to wear a big bra for it to not fall.

Small in chest, but stunning!!

I love with this dress. The M was tight in the chest/waist but fit the best in my hips!

Love this dress

Received many compliments. Although the fabric doesn’t stretch, it fits like a glove. I would rent it again.

Side up. I sized up a little too much ended up going with the large.

Super pretty great for vacation with a red blazer over.

Do not size up if you are petite!

I made the mistake of listening to the reviews and I ordered one size up. It’s too long and too big in the hips. I am a D cup and it’s even a little too loose on the top. Such a cute dress though! I am going to switch it out for my normal size.

Very chic. I wore it to theatre. I had to wear the large because it runs really small but I loved it.

I sized up 2 as recommended and this dress was unwearable… and I have a large bust so thought it would be ok. Didn’t wear.

See below Measurements for Size Small!

I wear size Small in Ronny Kobo. This dress came new with tags and I was soo excited to get it! The material and colors and style are delightful so it was depressing the sizing was so off. This fits much smaller than other Ronny Kobo dresses at the top in my opinion. Perhaps a very narrow body will fit this dress but here is what I measured: Width of top of dress = 32 inches (16.5 in across) Width of below bust line of dress= 26 inches (13.5 in across) My body measurement to correspond to top of dress (above bust line) = 35.5 inches My body measurement to correspond to below bust line = 30 inches So measure yourself before renting size Small! If your measurement is 26 inches or less below bust line and 32 inches or less above bust line then it will fit. If your measurements exceed this around the bust area, the dress will not zip up. Non-stretch material & design.

Cute but way too small

very pretty dress but runs so small. I’m typically a 4 in dresses. I got a M and could barely zip it up. It was skin tight. Unfortunately couldn’t wear. Size up at least by 2, wish I got a Large.

Too Small

M was way too small, and I’m a solid M in everything, including this brand. I’d probably need an XL in this. Not sure I want to waste a spot trying it, though

Unfortunately, way too small

This dress is gorgeous. I love the ruffles and the ruching, but I could not get this over my rib cage. This designer usually runs small but this is ridiculous, I’m 52 and 110 pounds and I could not zip up the extra small. Make sure to size up at least one or two sizes.

Size up 2?

I loved how this looked, it is beautiful but could not even come close to zipping it. I wear Ronny Kobo often and never have not been able to wear the item. I would size up maybe 2 sizes, one may not have been enough.

Sizing is way off

I sized up and it fit good in the midsection but was too large in the hips and chest. I think they used Barbie proportions for their dress form. Too bad because this dress is really cute in person.

No stretch and runs small

I couldn’t wear this dress because it was very, very small. I normally wear a L but this was more like a small/medium and short. The fabric has zero stretch. FYI.
