I have an hourglass figure and I am usually between US 4 and 6. Based on previous reviewers, I decided to size up. Bought an 8 in red during sale. Colour is as pictured. While the upper part of the dress fits perfect, the hips area is slightly loose instead of hugging me. Had I gone for size 6 though, the top part of the dress would have been too tight (I can imagine myself not being able to breathe due to the chest compression). That said, this is a gorgeous dress. Absolutely stunning! I look amazing in it. The material looks and feels expensive. That is something you can count on Black Halo. Moreover, I love how the lining is stiched together with the shell (outer fabric) so it is not a separate layer.
