If your aim is to get a muscular body for good looks and style then you should not follow the exact workout principles that bodybuilders follow. Of course, you'll need to use the big lifts squats, bench press and dead lifts to put on mass, but you should be cautious with them.
Do not allow yourself to over use these powerful mass gaining exercises. You should use those lifts to put on the ideal amount of mass on yur frame, then focus on increasing definition for your body.
You need to focus on adding muscle in the right places as well. A typical bodybuilding workout program will instruct you to add muscle on your entire body which is a common bodybuilding practice.
However, if your aim is to build muscle for good looks, you may not want to follow this advice, unless it'll give you the desired look you're after. It's best to avoid adding muscle in places that can ruin your look.
If you naturally have big legs and hips then you need to be extremely careful with squats or avoid using this lift all together to add more mass in these areas.
Some people have the idea that it's against bodybuilding principles to not use squats, but remember your aim is not to get accepted as a bodybuilder, you only want to do whatever is necessary to get a body that look good. So I'll say, if squats are not necessary for accomplishing your goal then don't use it.

When you're aiming for good looks you need to perform cardio. Cardio is important for helping you get at a low body fat percentage.
