Colorful Rolling Dice Dungeons & Dragons T-Shirt

I bought this as a gift for a huge D&D fan. Great quality t-shirt. Fits well

Bought this for me and simultaneously bought another shirt of the same size. According to each shirt size chart, there shouldn't be any issue, but there is. An XL shirt comes in a size closer to M. It was disappointing. While I know I can request an exchange, I am currently abroad and getting the exchange would mean almost paying for the shirt again.
