I followed the size chart, and ordered based on my measurements, and I'm a curvy girl. It fit perfectly. I'm 5'1", so it hits me right below the knees. I didn't have any of the fit issues that I've seen in other reviews. You don't really need the petticoat, but it hangs sort of sad if you don't wear one. I put a red ribbon belt on it instead of the black one that came with it. I thought it was cuter.
This is more a warning review! I ordered this dress originally in a large after reading other reviews as I am 5'9" and 150lbs but when I received the dress it had at least 2 extra inches in the waist. Other than the size I LOVED the dress; the cotton felt great and the shape was wonderful (posted picture of original dress). I have no idea how to sew so I decided to send it back and reorder the same dress in a medium. When it arrived I was so excited but as soon as I opened it I felt it was NOT the same dress. The second dress was mostly a polyester material and so thin you could see my tattoo on my stomach through the material and the sewing was terrible and uneven. I contacted the seller multiple times and he wouldn't tell me why the material was wrong. Finally after reading a little further I missed a warning in the description that states to MAKE sure you're buying from GK Queen as others are imitation and lower quality. I went backed and looked and sure enough the second time I bought was from some Aikan. So frustrated right now I'm just giving up on the dress as I've had nothing but bad luck with it.
This is my THIRD "color" of this dress this summer. I have worn all three to weddings and strangers were stopping me to compliment me on my dress. Classy, fun and timeless. Don't skip the petticoat and you'll bring down the house!
