[free] Lidl jersey (oversized medium?)

I bought this last week, tried it on at home and though it fit. Binned the receipt and packing.

But when I went to go for a cycle it seemed huge on me.
Can't return it as binned everything and not all that expensive so hardly worth the hassle of selling.

It's free to anyone who wants it, otherwise it will go in the clothes recycling in a week or two.

Size says medium but I am swimming in it. It's L or maybe XL
