Read the fine print
Read the fine print. The sizes are based on tiny Asians, not Americans. Large is not a US Large. A large for MildStyle is closer to a US Medium, perhaps even Small. This is confounded by their poor returns / exchange policy. They basically tell you "Hey you could ship it back to us in China, but that would be super expensive, so instead why not give the small shirt to a family member or friend and we will give you 10% off your next order?". No thanks. I'll take my business elsewhere and tell everyone to avoid this etailer. And yes, I am at fault for not reading the fine print.
