Convertible bridesmaid dress - with pockets!

I got this dress several years ago, wore it once to a wedding, and am just getting around to selling it. It’s a beautiful greenish blue color, and it was very comfortable and flattering! I had it hemmed- I’m 5’2” and I think wore 2 or 3 inch heels with it. It was an outdoor wedding, so you can see several spots that are stained, especially along the bottom of the dress. I think they could be treated to remove them. Fit is TTS otherwise.
