We all love Old Navy’s swing dresses because of the great fabric, lightweight feel, and they can be dressed up or dressed down! When I saw this new polka dot design, I just couldn’t resist! I would suggest sizing down if in between. I am wearing this dress in size XS which is one size smaller than my usual size. It is also available in plus sizes! For a little extra length, you can order it in the tall! I am 5’5″ for reference.
