It seems to me the trousers are a bit tight through the seat (see the pulling below the pocket button on the left side -- seems to indicate they are a bit tight through the seat/across the hips). Â Also, they look like the rise is perhaps a bit too long -- vide the appearance of excess material below the crotch on the full-length shot (Raphael3). Â Finally, they seem very full through the lower thigh, though this may be a personal preference of Kai. Also, I think the upper portion of the sleeves look a bit twisted or pulled in the full-length shots, particularly the first 2 shots. Â The torso/chest of the jacket looks very nice.
Regarding the fit. It is difficult to really tell the fit of a suit through static pictures. The cloth is going to fold here and there, depending on how a person stands. For these particular pictures, I had my arms a bit more forward than usual, to expose a bit more cuff. With my hands at my sides, the cuff just barely peeks out, and so I was bending my arms a bit, so the cuffs would show up better in the photo and I wouldn't be accused of the travesty of wearing a short sleeved dress shirt. That may explain the folds in the arms. There is a bit more fabric in the thighs and seat of this suit compared with some others, but I wanted it that way, as it is more comfortable given my build. I'm not sure about the picture, but the seat of this suit is pretty comfortable. I can sit, kneel, cross my legs easily (something I can't do with an off-the rack suit without alterations.) Overall, I'm happy with the fit. For me, it has just the right balance of following the lines of my body, but still allowing enough room to move.
