Im 52 misses size 12 always in dresses. I ordered an XL and it fit perfectly. It runs true to size. Its beautiful. Feminine. I plan on ordering more. I ordered the petticoat also. It can be worn either way. Go by your measurements and order. Very highly recommend this dress. I washed it after trying on. It washed very well. I didn't dry. I sprayed it with wrinkle remover and it looks great. Very happy.
