I originally purchased an 8 based on my measurements. It was pretty loose, and I replaced it with a size 6, which fit perfectly--I'm 140lbs/5'4". It was VERY long on me--I cut 6 inches off the bottom. I had a lot of trouble hemming it--it's so cheap that I would recommend just having a pro do the alterations. I actually ended up removing the hem job I did and just left the bottom unfinished. It did fray a bit, but it worked for a one-time wear. The red is a nice deep color. Overall, great dress for the price!
