This dress is life changing. So, SO comfortable. I wore a regular bra which is huge for me. My friend has been telling me for years to try a nap dress and I finally pulled the trigger, and I’m so glad I did. Will definitely get more. I did size down 2 sizes from my regular size. I am a 36D and usually wear size L/XL or 12/14 and I tried medium and small, and small fit best.
