Fred Perry Polo XL Short Sleeve Light Green

Hey I have a Fred Perry short-sleeve Polo light green size XL with black double piping at the end of arm. Unfortunately I can't fit into it anymore ... pit to pit is 20" it's a very slim fit compared to their hoodies and sweaters etc. FYI please note there is a small marking on the front of Polo I added a pic of it ... it's the last pic and it's barely visible unless looking at it up close if you have any questions please let me know thanks
