I originally bought this dress at the recommended size of medium and it was way too big. The dress is flowy so for me when it was too big it was too flowy. I wanted it to give me that feel without feeling like I was swimming in the dress. I ended up sending back the medium and getting a small and it was perfect. I am 5’6 and around 165. I am pear shaped and I have some legs (that I refer to as thunder and lightening lol). The small still flows and doesn’t cling and it fits perfect. I got this in dark green and had no transparency issues. Good quality fabric that doesn't feel heavy but isn’t see thru. I have washed it once and it washed well. A small note- I do wear slip shorts or bike shorts under most dresses just for comfort and still very flowy. I will say though that I wore this to the airport and had a backpack on which can make the dress ride up in the back. However, I also use a medium size adidas crossbody sling as a purse most of the time and it does not make it ride up. Like I said wore this flying and then to walk around Walt Disney World and was extremely comfortable. I want this dress in all the colors! Can dress it up or wear super casual (I wore it with adidas sambas). Great value for the versatility Only thing that would make it perfect would be if it had pockets!
