Nadine Merabi Katie dress. Size S/M which is about a size US 4 (it’s says 4-6 but this dress is on the smaller end of that). Please refer to Nadine Merabi’s sizing chart for measurements. This brand has sizing of S, S/M, M. The measurements on Nadine Merabi website are very accurate if you’re having trouble picking your size. This dress does not have any stretch. I did have the hips taken in 1/4 inch on each side on the top layer only to decrease sagging. (This dress has 3 layers. Slip lining, satin lining, beaded/sequin overlay.) Comes with dress bag and belt.
