Radcliffe Olive green 3 piece looking romper

This rumper is gorgeous. Unfortunately the photo doesn't reflect its true color, it is a vivid Olive green. Button front, Plead it baggy short bottom. Perfect for the more modest woman AKA not booty shorts 2 side pockets.. It appears to be more than one piece but everything is connected. What looks like a jacket can be opened up to what looks like a vest. That too can be opened up as well. Pre owned comment in great condition. Late eighties early nineties style Comes what they built Size 10 hello and however if it's a small or medium size 4/6/8
