This dress is so beautifully made very classy look very comfortable and flowy. I paired it with a slip underneath and I wear them everywhere. You don’t need a slip they are not see through. I myself enjoy a smooth look. I am 150lbs 5’5” and I ordered a size large because I wanted an oversized fit. A medium would have worked well also. I grabbed multiple colors don’t hesitate this fall I’ll throw a cardigan and boots on and it’ll transition from summer to fall nicely.
