Also random thought but I find when I spend a lot of time on SF i want to slim down so that I can wear more things. KG, for easy example, has a pretty great physique in that he still looks muscular but isnt bulky. When I spend time at my gym I just wanna become as big as i can.
Looking bulky (what you think isn't good for fashion) = muscles + higher bodyfat%
Muscular physique that most people still think look good = muscle + low bodyfat%
If you just want to look like you lift weights and still fit into clothes, it could be a point to not build your legs too much. I hate to say this but it would make more sense to focus on the chest, arms, shoulders and upper back. Kgfan does not have huge wheels but he do have a built upper.
If you want to pursue both, I would simply focus on building the muscles you think look good and allow you to fit into the clothes you like, while you keep a eye on what you eat and do some cardio.
