I wore this to an evening black-tie wedding. I was initially concerned that it would not be dressy enough, but after putting it on my fears were allayed. The slip underneath IS short, but I did not think it was an issue. I am 5' 7'' and about 128 lbs, somewhat curvy with hips. The length runs a little short - I wore 2 inch heels and was fine, could not have worn heels any higher without wearing the long. I received compliments ALL night. I felt very glamorous and stylish. It was so comfortable to dance in as well. I didn't want to return it!
