I ordered two of the "yellow old school" LetsRun shirts to see which I like the fit better on....
The large was way too big for me. Not only too long, but too baggy, as well. For a frame of reference, I'm 5'8" and 145 lbs (yes, I could lose a few pounds..but I enjoy going out to eat way too much). I like a bit of a looser fit and even this was too loose for me.
It's actually a really nice shirt. Still in the packaging (took it out to try on only) and includes the LetsRun sticket with it.
If someone out there wants the large, I will send it to you, completely free of charge...no need for any type of payment or anything. Drop your email in here (registered usernames only) or way to get a hold of you and we can go from there.
