amscan 9918660 Adults Avocado Tabard Fancy Dress Costume (Chest Size: 46")

Great

This is akin to wearing a photo of an avacado really, or some kind of kitchen apron that happens to be in the shape of an avacado.Sure its cheap compared to other options out there, but its far from the best looking.To maximise the effect I'd say pair it with a green top or something like that as the back is just visible straps. It's totally a low-effort and low cost costume. Depends on your standards for a costume as to whether this is going to be right for you and your needs.
