My wife is considering a Darien. We'd like to avoid multiple shipments trying to get the size correct. I have Aerostich gear so I know they will work with us, but nothing speaks like experience. Annie is 5'9" tall with most of her height in her legs; she wears a size 10-12 dress. Generally wears mediums in women's clothing and small in a man's. Any ladies out there that wear a Darien and can offer your experiences with sizing?
