Beautiful suit
I love it! It is very flattering. I normally wear a 6. I had to get an 8. It’s the best!

Hi Jill,
Thanks for your review!

Great suit but not long torso
I was excited to see comments suggesting this may have a long torso though they don't advertise it as such. I bought it with the hopes it would work for me as I'm 5'10" like the model in the photo but it didn't. Once I took it out to test (without anything underneath) I found it kept riding up my bum often. Very sad and bummed I can no longer get store credit for it. Otherwise, very comfortable fabric and stretch.

Hi Katie,
Thank you for the review. We apologize about the sizing. A customer service team member will reach out to you shortly to help you with sizing and answer any questions.
Bummer
I’m 5 ft tall 110 lbs. I generally wear a 0-2 in everything. I ordered a small and it was way too small. I ordered a medium and it was still too snug. What a bummer. I’m not sure why a company wouldn’t want to make women feel good about their bodies and make their suits true to actual size. I returned this suit.
