I sized up to size 6 and it fit like a size 4. The length was way too long so I had to pay a tailor to take it up. I’m 5”4 and weigh 135 lbs. It looked beautiful on the day of the wedding I attended.Love the color and the fit of the dress. I had it shortened and had it taken in a little on the top. The dress is fully lined and is stunning.I LOVE THE COLOR OF THIS DRESS AND THE GENERAL FIT. I USUALLY WEAR A SIZE 8 BUT THIS IS A VERY SLIM CUT AND HAD TO GO UP 2 DRESS SIZES. 5'4" 145 LBSThis is a stunning gown. It is really a pretty bright shade of periwinkle, but it runs really really small. I am usually a perfect size 8, 5'8" and 145 pounds, but I could barely breathe in this one. Very pretty though.This is a beautiful dress. The fabric is high quality, beautiful color and made very well.I wore this at my brother's wedding and it was gorgeous.Fit perfectly! Amazing last minute buy!!Really stunning dress, very comfortable, beautiful color. I’m 34-25-36 and the 4 was a perfect fit. I’m 5’5 and had to have the length altered about 4 inches. The only reason I gave four stars is because the fabric snagged just a little tiny bit after I wore it— which I wouldn’t expect from a $400 dress. But all in all, worth it!
