Great product for the price
Size: Medium, Color: Green
Decent quality and fabric. Looks and great and and fairly comfortable. Sizing wasn’t exactly what I normally wear. I recommend getting a size up. Other than that it was just fine.

Poor quality.
I know this is costume wear but it’s so cheaply made it barely lasted one St Patty’s day at work.
