This post is an example of how to think when thrift shopping. This "dress" is really just a big shirt ass shirt, but I saw the potential in it as a dress. Basically, almost any size will work out so long as its not too small - to which there's no coming back from unless you love tube tops.
Also, this is one of the only times that you'll see me rocking the purple - not really my color. However, I really liked the floral print & separation within the blouse. So in summary, it doesn't hurt to take risks when we're talking about $5-8 garments. If it works it works, but there's no love lost at the end of the day.
