Both suits have short front balance due to your erect posture. Dark suit has more shape through the body. Tan suit is boxy and the shoulders are wide. Both have a roll under the collar due to your shoulder blades. The tailor may want to lower the collar but has to do so carefully. Best but most expensive is to shorten the back at the shoulders to adjust for your posture and make the shoulder with more fullness over your blades. Takes a coat maker's skill and expertise and may run into big bucks. Might have trouble finding someone to do that type of alteration.
