Heres the thing i belive you can look like a 60's bodybuilder naturally i know a few guys who are natural and look close to the guys like larry scott,dave draper etc also it depends on how short you are. if your short then with a shirt on you can reseble a bb pro i know a guy whos 5'4 hes 205 naturally with a shirt on he looks humongous barrel chest everything. but also steroid muscle looks diffrenty then regular i ve seen peopel weigh 200 naturally and 200 juiced they just look diffrent , cant comapre but also the regular persons perception of big is liek brad pitt in fight club so you can still be bigger then m,aybe people
