This dress is a size 2P, but runs large. Based on the website, I was between a size 4 and 6 the 2 fit like a glove! I wore this to my spring wedding and it was perfect! I am 5'0" and I wore 4 inch heels and the dress grazed the ground. It is unaltered and I thought fit me perfectly! It is fully lined with a built in bra. The only issue that I've seen is that the top two buttons in the back are starting to come loose and would maybe need to be sewn on a little more tightly. It is clean and ready for you to wear!
