Earthbound blue/gray tie dye pattern romper with cut out at belly Size S

I have loved this little romper since the day I bought it! I have worn it to fancy occasions as well as casual get-togethers. I believe it is cotton but I can't find an inner tag. It is machine washable. The top is gathered at the bust, just above the belly cut-out. There is wide elastic at the waist but it isn't too tight. The back is slightly open with a zipper closure that ends part way up and then a little button closure at the very top. It is extremely soft and soooo comfortable! I am finally cleaning out my closets so decided to let someone else enjoy this piece as much as I have.
