Baggy =/= no fit.
Look at the shoulder seams; perfect. Look at the shirt at the waist. Had it been any more narrow, it would look silly with the fullness of everything else. Wider, it would billow. The only nitpick could be the neck, which seems too small, but as I doubt that shirt was ever made to be worn with a tie (and the top button to be buttoned), I suspect that's just right as well.
Take away the brand, I bet you still have 100+ thumbs. Take away the name (as MoK is, I think, a well regarded fellow), I bet you still have 70+.
