First off this gi is beautiful, the material and all, but To answer the question, yes this gi is no doubt for the tall, lean skinny guy. Example, I got it in white for my son, He's 11 years old 5"1 and 105 lbs. I purchased the A0, after shrinkage, this gi fits pretty much like a glove as if it is tailor made (arm length and leg length. . His measurements 5"1 , 105lbs, 27 waist, 30,5 chest, 35.5 outseam, 28 inseam. There is a you tube video that gives a closeup on this gi and a review. Personally I would say this gi isn't for the stocky type.
